Ingo has some very good points. I think this might be worth doing in
some form or other, but if it's worth a full release cycle is less
certain to me:

Essentially we already do this for every release, where the last
couple of weeks are strictly bugfixes only. While it's not what you're
proposing, the end result sounds to me more like a "forced" extension
of the -rc cycle by several weeks to let more of those fixes come in.

If you're doing a 3.20/4.0 that is bugfixes only, then why release
3.19 at all? If the only difference between the two is said fixes,
we'd be better off just holding on until the latter is released. Which
again comes back to in practice extending the release by several more
weeks of late -rcs.

The only benefit I can think of to make a 3.19 release is to pick up
more users, if some of them avoid -rcs but do use full releases
shortly after they are tagged. I don't know how common that is though.
