I think we have done that, piece by piece, where it was actually buying us
something.  In particular we've gradually moved the goalposts for *printf
compliance, and I'm proposing here to move them a bit further.  I'm not
sure what "we're going to insist on C99" even means concretely, given
this position ...

Sure.  It's been a long time since anybody worried about those as
optimization targets, for instance.  Still, I'm not in favor of
actively breaking compatibility unless it buys us something.
