I'd expect that for most users (at least that's the case for me), 99% of
the faces are not changed by the call to internal-merge-in-global-face,
so it seems fair to let internal-merge-in-global-face do the update, so
it can optimize it away when no change were performed.

That doesn't answer my point, which is that this problem you describe has
been with us for ever, and so it's irrelevant to the question, AFAICT.
Or are you saying that my proposal would make it somehow worse?
