    # For backwards compatibility with existing lockfiles, if the most specific

    # best platform variant at materiliazation time. For previous bundler
    # versions (before 2.2.0) this was always the case (except when the lockfile
    # only included non-ruby platforms), but we're also keeping this behaviour
    # on newer bundlers unless users generate the lockfile from scratch or
    # explicitly add a more specific platform.
