Of course it is, but that is not the point that is being discussed: nobody
proposed doing these transformations at -O2. If you don't want these
transformations, then don't switch on -fsomething. But if, for some
certainly valid reason you don't want to use these transformations, why
shouldn't other people have valid reasons to request them?
