No, it's very much possible and easy, but if we're in such a situation
before display-buffer is called (i.e. it was not considered a problem
before we called display-buffer), why should we assume that
display-buffer should change it?

This reasoning is currently applied to raise-frame and I don't see why
we should use a different reasoning for make-frame-visible (after all,
a frame buried under other frames is just as invisible as an iconified
frame).
