Yeah, I think removing 24.4 and 24.5 things would be premature, but the
older stuff should be fine.

We've changed our naming methodology -- we used to have major and minor
releases, but with Emacs 27 we ditched that, so the obsoletion strategy
has to be adjusted a bit.

Yup.  I think everything obsoleted before Emacs 24.3 should be up for
removal in Emacs 29 (since that'd be about a decade old when Emacs 29 is
released), but perhaps Eli has a different opinion.  Eli?
