    OPINION OF THE COURT
    ___________
    VANASKIE, Circuit Judge.
    These asbestos cases involve the availability of the
    “bare-metal defense” under maritime law. The defense’s basic
    idea is that a manufacturer who delivers a product “bare
    metal”—that is without the insulation or other material that
    must be added for the product’s proper operation—is not
    generally liable for injuries caused by asbestos in later-added
    materials. A classic scenario would be if an engine
    manufacturer ships an engine without a gasket, the buyer adds
    a gasket containing asbestos, and the asbestos causes injury to
    a worker. May the manufacturer be held liable? Some courts
    4
    say no—never. Others rely on a more fact-specific standard
    and ask whether the facts of the case made it foreseeable that
    hazardous asbestos materials would be used. Neither this
    Court nor the Supreme Court has confronted the issue.
    In that void, we survey bedrock principles of maritime
    law and conclude that they permit a manufacturer of even a
    bare-metal product to be held liable for asbestos-related
    injuries when circumstances indicate the injury was a
    reasonably foreseeable result of the manufacturer’s actions—
    at least in the context of a negligence claim. The District Court
    had instead applied the bright line rule approach and entered
    summary judgment against the plaintiffs. We will vacate the
    entry of summary judgment on the plaintiffs’ negligence
    claims, affirm the entry of summary judgment on the plaintiffs’
    product liability claims (which we conclude were abandoned
    on appeal), and will remand, for further proceedings.
    I.
    Appellants Roberta G. Devries and Shirley McAfee are
    the widows of deceased husbands who served in the United
    States Navy. Each couple filed a Complaint in Pennsylvania
    state court alleging that the husband contracted cancer caused
    by exposure to asbestos. Devries alleges that on the U.S.S.
    Turner from 1957-60, her husband was exposed to asbestos-
    containing insulation and components that were added onto the
    ship’s engines, pumps, boilers, blowers, generators,
    switchboards, steam traps, and other devices. McAfee alleges
    her husband was similarly exposed through his service on two
    ships and in the Philadelphia Naval Shipyard.
    Devries and McAfee named a number of defendants, of
    which Appellee manufacturers (“Manufacturers”) are a
    5
    subset.1 The Manufacturers each made their products “bare
    metal,” in that if they manufactured an engine, they shipped it
    without any asbestos-containing insulation materials that
    would later be added.
    Devries and McAfee’s Complaints each allege claims
    of negligence and strict liability. The Manufacturers removed
    to the Eastern District of Pennsylvania and invoked the bare-
    metal defense in support of their respective summary judgment
    motions, arguing that because they shipped their products bare
    metal, they could not be held liable for the sailors’ injuries.
    The District Court agreed and granted the Manufacturers
    summary judgment motions.
    Devries and McAfee each appealed separately, raising
    an issue as to whether the District Court’s decision addressed
    their negligence claims. We summarily remanded with
    instructions that the District Court address the negligence issue
    and also consider a split in authority as to whether a bright-line
    rule or a fact-specific standard governed the bare-metal
    defense’s availability. In re Asbestos Prods. Liab. Litig., No.
    15-2667, Order (3d Cir. May 12, 2017) (McAfee); In re
    Asbestos Prods. Liab. Litig., No. 15-1278, Order (3d. Cir. Feb.
    5, 2016) (Devries).
    On remand, the District Court applied the bright-line-
    rule version of the bare-metal defense, and clarified that
    summary judgment had been entered in favor of the
    1
    The Appellee-Manufacturers are Air & Liquid
    Systems Corp., CBS Corp., Foster Wheeler LLC, General
    Electric Co., IMO Industries Inc., Warren Pumps LLC, and
    Ingersoll Rand Co.
    6
    Manufacturers on both the strict liability and negligence
    claims. The Court reasoned that the rule approach was best
    because, according to the Court’s view of the precedents,
    maritime law favors uniformity and the rule approach was the
    majority view.
    Devries and McAfee appealed for a second time. We
    consolidated their appeals and ordered coordinated briefing.
    II.
    The District Court had federal-officer jurisdiction under
    
    28 U.S.C. § 1442
    (a)(1), and maritime jurisdiction under 
    28 U.S.C. § 1333
    (1). We have jurisdiction under 
    28 U.S.C. § 1291
    . We review the District Court’s grant of summary
    judgment de novo. Faush v. Tues. Morning, Inc., 
    808 F.3d 208
    ,
    215 (3d Cir. 2015).
    III.
    The key question in this case is the bare-metal defense’s
    availability: When, if ever, should a manufacturer of a product
    that does not contain asbestos be held liable for an asbestos-
    related injury most directly caused by parts added on to the
    manufacturer’s product? Neither the Third Circuit nor the
    Supreme Court has addressed the question, and the courts from
    other jurisdictions that have are split. Some courts apply a
    bright-line rule, holding that a manufacturer of a bare-metal
    product is never liable for injuries caused by later-added
    asbestos-containing materials. See, e.g., Lindstrom v. A-C
    Prod. Liab. Tr., 
    424 F.3d 488
    , 492, 494-97 (6th Cir. 2005);
    Cabasug v. Crane Co., 
    989 F. Supp. 2d 1027
    , 1038-43 (D.
    Haw. 2013). Others apply a more fact-specific standard,
    stating, for example, that a bare-metal manufacturer may be
    7
    held liable if the plaintiff’s injury was a reasonably foreseeable
    result of the manufacturer’s conduct. See, e.g., Quirin v.
    Lorillard Tobacco Co., 
    17 F. Supp. 3d 760
    , 768-70 (N.D. Ill.
    2014) (determining whether the addition of asbestos material
    was “foreseeable” by asking whether addition of asbestos-
    containing materials was “inevitable,” and whether those
    added materials were “necess[ary]” or “essential” to the
    manufacturer’s product); Chicano v. Gen. Elec. Co., 
    2004 WL 2250990
    , at *6 (E.D. Pa. Oct. 5, 2004) (asking if the addition
    of asbestos-containing materials was “foreseeable”).2
    In addressing this question, we (1) examine the
    doctrinal roots of the bare-metal defense, and (2) address how
    2
    Illustrative of the unsettled status of this issue, we
    recently certified to the Pennsylvania Supreme Court the
    question of whether under Pennsylvania law a manufacturer of
    a product can assert the bare metal defense in the context of a
    negligent failure to warn claim arising out of exposure to
    asbestos. See In re Asbestos Products Liability Lit. (No. VI),
    Crane Co., No. 16-3704 (3d Cir. Sept. 27, 2017) (Petition for
    Certification of Question of State Law).
    Whether, under Pennsylvania law, a manufacturer has a duty
    to warn about the asbestos-related hazards of component parts
    it has neither manufactured nor supplied.
    If such a duty exists, what is the appropriate legal test to
    determine whether the company is in fact liable for failing to
    warn about the risks of asbestos?
    
    Id. at 11
    .
    8
    it should be applied in Devries and McAfee’s negligence
    actions.
    A.
    The doctrinal root of the bare-metal defense has proved
    to be a particularly vexing question. Some courts have rooted
    the defense in causation: When if ever can it be said that a
    bare-metal manufacturer causes an asbestos-related injury?
    See, e.g., Thurmon v. Ga. Pac., LLC, 650 F. App’x 752, 756
    (11th Cir. 2016) (“the ‘bare metal defense’ is, essentially, a
    causation argument”). Others locate the defense in duty: Can
    a manufacturer’s duty to act with reasonable care with respect
    to reasonably foreseeable risks and plaintiffs, be said to extend
    to asbestos-related injuries? See, e.g., Quirin, 17 F. Supp. 3d
    at 767-70 (reviewing the issue as one of “legal duty”). The
    question is more than academic. If the elemental root is duty,
    the defense should be expected to operate differently in strict
    liability as compared to negligence, because a defendant’s duty
    of course differs between the two types of actions. See Chesher
    v. 3M Co., 
    234 F. Supp. 3d, 693
    , 700-03 (D.S.C. 2017)
    (holding that the defense should apply in a weaker fashion in a
    negligence action, as compared to strict liability). The opposite
    might be true too—the defense should operate in similar
    fashion in both negligence and strict liability if it is rooted in
    causation, because the proximate cause inquiry cuts across the
    two types of actions. See, e.g., Lindstrom, 
    424 F.3d at 492
    (suggesting the defense applies similarly under “both
    negligence and strict liability theories”).
    We find that both approaches are correct: the defense
    is rooted in both duty and cause because its keystone is the
    concept of foreseeability. When parties debate the bare-metal
    defense, they debate when and whether a manufacturer could
    9
    reasonably foresee that its actions or omissions would cause
    the plaintiff’s asbestos-related injuries. The bright-line rule
    approach says it is never reasonably foreseeable, and the fact-
    specific standard approach says it sometimes is. This debate
    over foreseeability sounds in both duty and cause, because
    foreseeability is a concept embedded in each element. See
    Gibbs v. Ernst, 
    647 A.2d 882
    , 891 (Pa. 1994) (highlighting “the
    common law notion of foreseeability as found in the concepts
    of duty and proximate cause”). In the duty element in a
    negligence action, foreseeability limits a defendant’s liability
    to only the risks and plaintiffs that are reasonably foreseeable.
    See Restatement (Third) of Torts: Phys. & Emot. Harm § 7,
    cmt. j (2010 Am. Law Inst.) (acknowledging “widespread use”
    of foreseeability as an aspect of the duty of reasonable care,
    despite the Restatement’s disagreement with such an
    approach). And in proximate cause, foreseeability limits a
    defendant’s liability to only the injuries that are a reasonably
    foreseeable result of the defendant’s actions. Id. § 29, cmt. j
    (discussing foreseeability as an aspect of proximate cause in
    both negligence and strict-liability actions).3 Thus, the bare-
    3
    Instead of starting from subject-specific asbestos
    cases, we begin our focus with the ordinary and traditional
    principles of maritime and tort law, as exemplified in the most
    reliable treatises and restatements. Cf. M&G Polymers USA,
    LLC v. Tackett, 
    135 S. Ct. 926
    , 929-30 (2015) (abrogating a
    circuit’s labor-law-specific rule for contract interpretation, and
    calling on lower courts in labor-law cases to still adhere to
    “ordinary” and “traditional” principles of contract law);
    Paroline v. United States, 
    134 S. Ct. 1710
    , 1719-20 (2014)
    (citing, as authority for the federal common law of proximate
    10
    metal defense is nothing more than the concept of
    foreseeability, as embedded in the duty of reasonable care in a
    negligence action and the proximate cause standard in a
    negligence or strict-liability action, as applied to the facts of a
    certain subset of asbestos cases.
    This dual-elemental home for the defense does not,
    however, totally explain when or whether the defense’s
    application should differ from strict-liability to negligence. It
    might be that the defense could apply the same in both types of
    actions, because of the shared proximate-cause element. Or
    the differences in the two actions’ duty elements might mean
    the defense is more forceful in one action than the other. See,
    e.g., Chesher, 234 F. Supp. 3d at 700-03 (holding that the
    defense is weaker in negligence and stronger in strict liability,
    because in strict liability the manufacturer’s duty is limited to
    the product, but with negligence the duty extends further); Bell
    v. Foster Wheeler Energy Corp., No. 15-6394, 
    2016 WL 5780104
    , at *5-7 (E.D. La. Oct. 4, 2016) (same). And of
    course the facts of a given case could be the most important
    variable.
    We need not settle these doctrinal distinctions today,
    because Devries and McAfee waived their strict liability claim
    in this appeal. As a general matter, an appellant waives an
    argument in support of reversal if it is not raised in the opening
    brief. McCray v. Fidelity Nat’l Title Ins. Co., 
    682 F.3d 229
    ,
    241 (3d Cir. 2012). Here, in this appeal Devries and McAfee
    focused the entirety of their briefing on their negligence
    claims, yet attempted to also incorporate their strict-liability
    cause, the Restatement (Third) of Torts, Prosser and Keeton’s
    treatise on torts, and LaFave’s treatise on criminal law).
    11
    claim through a footnote: “By concentrating on [negligence]
    issues in this brief, Appellants do not waive any issues argued
    in their original briefs as to Defendants’ liability under [the
    strict liability claims].” (Appellants’ Br. at 2 n. 1). This
    attempt to shoehorn in an argument outside the briefs is
    insufficient to raise an issue on appeal. See John Wyeth &
    Brother Ltd. v. CIGNA Int’l Corp., 
    119 F.3d 1070
    , 1076 n. 6
    (3d Cir. 1997) (stating that “arguments raised in passing (such
    as, in a footnote), but not squarely argued, are considered
    waived”); see also Skretvedt v. E.I. DuPont De Nemours, 
    372 F.3d 193
    , 202-04 (3d Cir. 2004) (declining to consider
    arguments not properly raised and therefore waived). In
    particular, it fails to give fair notice of the claims being
    contested on appeal. Thus, Devries’s and McAfee’s waiver of
    their strict-liability arguments means that we will affirm the
    District Court’s decision to that extent, and need not fully
    explore the precise contours of the defense’s distinctions in
    strict liability and negligence, beyond the unifying principle of
    foreseeability.
    B.
    For the negligence claims, rooting the bare-metal
    defense in foreseeability does not on its own resolve the issue,
    because the split in authority can be characterized as a debate
    over what a bare-metal manufacturer could reasonably
    foresee—no asbestos-related injuries, see, e.g., Lindstrom, 
    424 F.3d at 492, 494-97
    , or some, see, e.g., Quirin, 17 F. Supp. 3d
    at 769-70.
    12
    These two choices raise familiar tradeoffs between rules
    and standards.4 A rule is a legal directive that attempts to
    capture a background principle into an easy-to-apply form that
    is predictable and efficient. A speed limit is a good example:
    its goal is road safety, but because liability turns on speed
    rather than the amorphous definition of “safety” itself, it is
    easier for drivers, police, and insurers to shape their conduct
    accordingly. Rules have downsides though too, in that they
    necessarily result in errors of over- and under-inclusion. In the
    case of the speed limit, it furthers the policy of road safety, but
    does so imperfectly: speedy drivers get punished even if they
    speed safely, and slow drivers go free even if they amble along
    haphazardly.
    A standard, on the other hand, collapses the background
    principle into the actual legal directive, resulting in better
    accuracy and “fit” with the underlying purpose, and fewer
    errors of over- and under-inclusion. Another road-safety
    example would be a reckless-driving prohibition that simply
    prohibits driving that is “reckless.” Such a prohibition is less
    predictable and efficient than the speed limit, in that it is harder
    to predict what a decisionmaker will find to be “reckless” than
    whether he or she will agree that 76 miles per hour exceeds a
    4
    For a review of the characteristics and tradeoffs of
    rules and standards, see Bryan A. Garner et al., The Law of
    Judicial Precedent 78 (2016) (noting that “rules and standards
    . . . denote different levels of specificity for norms” and
    “judicial holding[s]”); Kathleen M. Sullivan, The Supreme
    Court, 1991 Term—Foreword: The Justices of Rules and
    Standards, 
    106 Harv. L. Rev. 22
    , 58-59 (1992).
    13
    70 m.p.h. speed limit. But liability better tracks the actual goal
    of road safety, because almost all “reckless” drivers are unsafe.
    The point is there are tradeoffs, and courts face those
    tradeoffs in choosing an approach to the bare-metal defense.
    The rule-based approach is efficient and predictable—bare-
    metal manufacturers are simply not liable—but the downside
    is some deserving sailor-plaintiffs will not receive their due.
    On the other hand, the standard-based approach is bound to be
    less predictable and less efficient, because the standard’s fact-
    centered nature will push more cases into discovery, see, e.g.,
    Quirin, 17 F. Supp. 3d at 771-72 (denying defendant’s motion
    to dismiss after applying the standard), but the most-deserving
    sailor-plaintiffs are less likely to be denied compensation.
    Thankfully, we do not weigh these tradeoffs in a
    vacuum.       Maritime law is undergirded by established
    principles, at least four of which are implicated here. First and
    perhaps foremost, maritime law is deeply concerned with the
    protection of sailors, due to a historic and “special solicitude
    for the welfare of those men who undertook to venture upon
    hazardous and unpredictable sea voyages.” Moragne v. States
    Marine Lines, Inc., 
    398 U.S. 375
    , 387 (1970). This “special
    solicitude” developed “unknown to the common law,” and so
    maritime law is at times more lenient toward a sailor than a
    state’s common law may be to a similarly-situated plaintiff. 
    Id.
    This divergence is acceptable if not appropriate because the
    “humane and liberal character of” maritime law counsels that
    it is better “to give than to withhold the remedy” wherever
    “established and inflexible rules” do not require otherwise. 
    Id.
    (quoting The Sea Gull, 
    21 F. Cas. 909
    , 910 (C.C. Md. 1865)).
    For example, in Moragne v. States Marine Lines, the Supreme
    Court made it permissible for maritime plaintiffs to bring
    wrongful death actions even though the common law
    14
    disapproved of such actions. 
    398 U.S. at 381-88, 408-09
    . In
    arriving at that holding, the Court explicitly referenced and
    discussed maritime law’s special solicitude for sailor safety
    and how that solicitude permitted maritime law to have more
    sailor-friendly rules than the common law. 
    Id. at 386-88
    .5
    Here, maritime law’s special solicitude for sailors’
    safety similarly favors the adoption of the standard-like
    approach to the bare-metal defense. A standard will permit a
    greater number of deserving sailors to receive compensation,
    and compensation that is closer to what they deserve. Given
    that results for sailor-victims will differ under a rule as
    compared to a standard, and since no “established” or
    “inflexible” rule prohibits the more forgiving standard, the
    “humane and liberal character” of maritime law counsels that
    we follow the standard. Even if certain states’ common laws
    would call for a more stringent rule, maritime law’s more
    liberal attitude permits us to diverge from that path.
    Second, maritime law is built on “traditions of
    simplicity and practicality,” Kermarec v. Compagnie Generale
    Transatlantique, 
    358 U.S. 625
    , 631 (1959), but that principle
    cuts in both directions and does not provide much guidance.
    On one hand, “simplicity” might be seen as favoring the rule-
    based approach, because simplicity is related to predictability,
    and it is easier to predict how a rule will apply than a standard.
    5
    Moragne’s holding was based most directly on
    principles other than the special solicitude for sailor safety, but
    the special solicitude was still crucial to the Court’s decision
    because it explained why the Court’s ruling was appropriate
    even though it likely diverged from the common law.
    Moragne, 
    398 U.S. at 386-88
    .
    15
    On the other hand, “simplicity” could also be seen as favoring
    a foreseeability-based standard, because simplicity is related to
    familiarity, and foreseeability is such a familiar and key part of
    tort law. See id. at 631-32 (choosing to adopt a familiar
    standard over a “foreign” and “alien” rule while invoking
    maritime law’s “traditions of simplicity and practicality”).
    The third and fourth principles implicated in this case
    are also not particularly helpful. Maritime law has a
    “fundamental interest” in “the protection of maritime
    commerce,” Exxon Corp. v. Cent. Gulf Lines, Inc., 
    500 U.S. 603
    , 608 (1991) (quoting Sisson v. Ruby, 
    497 U.S. 358
    , 367
    (1990)), and seeks out “uniform rules to govern conduct and
    liability,” Foremost Ins. Co. v. Richardson, 
    457 U.S. 668
    , 674-
    75 (1982). Here, the parties all argue these two principles
    encourage the Court to side with whatever side is winning in
    the split in authority. The idea is that the sooner one side wins
    out over the other, the sooner the split in authority is ended and
    the goals of seamless commerce and uniformity of rules will
    be achieved. The rub, however, is determining which view is
    the majority. The bright-line rule could be said to be in the
    lead because it has on its side the Sixth Circuit, the only court
    of appeals to weigh in. Lindstrom, 
    424 F.3d at 492, 494-97
    .
    The standard could similarly be said to be the majority view
    because the courts that have confronted the question most
    recently have generally favored the standard, and have done so
    after a much more thorough analysis than that found in the
    Sixth Circuit’s opinion in Lindstrom, which was decided much
    earlier in the debate over the bare-metal defense. Compare
    Chesher, 234 F. Supp. 3d at 696-712 (analyzing in painstaking
    detail the split in authority and adopting a version of the
    standard); Bell, 
    2016 WL 5780104
    , at *3-7 (same), with
    Lindstrom, 
    424 F.3d at 494-97
     (not mentioning the split in
    16
    authority). We need not decide which approach is winning in
    terms of wins and losses—it is enough that the score is too
    close for us to say that the goals of seamless commerce and
    rule-uniformity push in one way or the other.
    In sum, the special solicitude for the safety and
    protection of sailors is dispositive, because it counsels us to
    follow the standard-based approach, and none of the other
    principles weigh heavily in either direction. The standard-
    based approach is the one we will therefore follow:
    foreseeability is the touchstone of the bare-metal defense; a
    manufacturer of a bare-metal product may be held liable for a
    plaintiff’s injuries suffered from later-added asbestos-
    containing materials if the facts show the plaintiff’s injuries
    were a reasonably foreseeable result of the manufacturer’s
    failure to provide a reasonable and adequate warning; and
    although cases will necessarily be fact-specific, already-
    decided precedents show, for example, that a bare-metal
    manufacturer may be subject to liability if it reasonably could
    have known, at the time it placed its product into the stream of
    commerce, that
    (1) asbestos is hazardous,6 and
    (2) its product will be used with an asbestos-
    containing part,7 because
    6
    See Bell, 
    2016 WL 5780104
    , at *5.
    7
    See 
    id. 17
    (a) the product was originally equipped
    with an asbestos containing       part       that
    could reasonably be expected to be replaced over
    the    product’s lifetime,8
    (b) the manufacturer specifically directed
    that the product be used    with an asbestos-
    9
    containing part, or
    (c) the product required an asbestos-
    containing part to function properly.10
    These may or may not be the only facts on which liability can
    arise. The finer contours of the defense, and how it should be
    applied to various sets of facts, must be decided on a case-by-
    case basis.
    IV.
    Finally, the Manufacturers advanced two alternative
    arguments in support of an affirmance on the negligence
    claims. They argued (1) insufficient evidence had been
    presented as to causation and was fatal to Devries and
    McAfee’s claims, and (2) the government-contractor defense
    should insulate the Manufacturers from liability. These
    arguments were also presented below, but the District Court
    8
    See Chesher, 234 F. Supp. 3d at 714; Quirin, 17 F.
    Supp. 3d at 769-71.

    See Bell, 
    2016 WL 5780104

    Supp. 3d at 769-70.
    18
    declined to rule on them because its bare-metal-defense
    holding was sufficient to enter summary judgment in favor of
    the Manufacturers. The Manufacturers urge us to address them
    now, on the grounds that we may affirm a judgment for any
    reason supported by the record. Brightwell v. Lehman, 
    637 F.3d 187
    , 191 (3d Cir. 2011). Addressing alternative grounds
    for affirmance, however, is a matter left to our discretion. See
    Gov’t of the V.I. v. Walker, 
    261 F.3d 370
    , 376-77 (3d Cir.
    2001) (declining to reach arguments raised before but not
    decided by the lower court, and instead remanding). Given that
    we are without the benefit of the District Court’s well-regarded
    expertise, and the parties’ briefing and oral argument was
    appropriately focused on the bare-metal defense, we will leave
    the insufficient-evidence and contractor-defense arguments to
    be dealt with on remand.
    V.
    In conclusion, maritime law’s special solicitude for the
    safety and protection of sailors counsels us to adopt a standard-
    based approach to the bare-metal defense that permits a
    plaintiff to recover, at least in negligence, from a manufacturer
    of a bare-metal product when the facts show the plaintiff’s
    injuries were a reasonably foreseeable result of the
    manufacturer’s conduct. We will affirm the decision of the
    District Court with respect to Devries and McAfee’s strict
    liability claims, and remand for further proceedings on their
    negligence claims consistent with this Opinion.
