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.
