That one isn't a rabbit hole, by all means, go ahead and delete that
usage, you are unlikely to find broken "$@" in any shell anyone would
actually want to use any more - that was a truly ancient bug being
worked around, as distinct from a difference from what is required,
which return being ignored in a script is.
