I suppose it's plausible, since the addition is transparent. We currently have something along the lines of sh being traditional Bourne shell, ksh and being more or less a superset of sh (though somebody pointed out a few weeks ago that ksh doesn't seem to have the effect of sh_file_expansion). Given that there are differences between ksh and posix, a new option would probably be necessary. However, the only use of posix would be to switch to it automatically in the appropriate place. If you have to trigger it by hand it's too late for most of the places where people want to guarantee Posix compliance. How would that be triggered?
