So, we've resolved this particular API in question
(css.document.MediaDescriptor) since that one was, although marked
'published', practically equivalent of being unpublished.

But I still have concerns in this area.  What if we discover an API that
should be (or should've been) unpublished way after the initial 4.0
release?  This may happen as we venture into areas where nobody has
really ventured into up until now, and discover some obscure use of
"published" API which hinders further rework unless the API is
unpublished.  Since we still have lots of areas in our code base where
nobody has stepped up to claim maintainer-ship, this is a very likely
possibility.

The published vs. unpublished is something of a red herring here. The real issue is if there is a problem you want to fix for a micro release and the fix requires incompatible changes. The solution is as always, if the benefits are considered higher than the risks, then make the incompatible change, otherwise don't (i.e., postpone indefinitely or postpone until the next minor or even major, where the perceived risk might be smaller).

The hitch with announcing changes in micro releases is that the lexicographical order of release numbers does not necessarily match the chronological order of releases, so what does it mean if some change is in "since LO 4.0.2" if LO 4.1 has been released before LO 4.0.2?
