Right. OTOH, there are research papers defending algorithms to somehow
automatically produce optically scaled fonts given various hints [0,1]
and my understanding is that MetaFont, for instance, already supports
it. So there are also reasons to think that such fonts are not (going
to) be rare.

Well, I'm afraid you are right in that there are higher priority
issues. :-)
