This, along with other magic variables, is the reason I don't use bash
as /bin/sh.  I'd like to have a ./configure option to remove much of
the special handling for specific variables - no automatic setting,
unsetting, exporting, or unexporting for noninteractive shells (or as
little as possible), so the environment remains intact.  Offhand, I'd
say IFS, OPT*, and maybe PPID should still be set (but not exported),
and I don't mind BASH* (as long as they're not exported), but I don't
want my /bin/sh to touch PS*, *UID, *GID, *TYPE, HOSTNAME, or most
others.  Would such an option be accepted?  Do you want to work on it,
or should I?
