First, it is documented:
Functions may be exported so that subshells automatically have them
defined with the -f option to the export builtin.
(Good luck finding that if you didn't know to look for it, though.)
Second, it's "useful" in niche cases like this:
foo() { ...; }
export -f foo
find . -type f -exec bash -c 'for f; do foo "$f"; done' _ {} +
So, if Chet removes the feature, it would probably break something that
someone cares about. Maybe there could be a compile-time option to
disable it. Maybe there already is -- I didn't look.
