no, that should be done no matter what -O options there are.
more -O options create more issues that have to be checked, and
making sure that 5 -O options work sensibly is a lot simpler than
making sure 4**5 -O options work sensibly.
and anyone who wants to play with all the -f flags is probably
going to be savvy enough to handle the problems they cause. the
-O flags should be simple and reliable for general users.
