Rather than altering the behavior of an existing option, I'd vote for
a new switch for such checks, maybe -fiso-strict?  That would preserve
the existing ISO functionality for those of us who are happy with
that, and the accompanying documentation can spell out the significant
performance implications of the stricter option.

In any case, having a simple way to select the equivalent of the
current -fiso mode would be helpful.
