It would be useful to have some automated testing of :core packages on
older versions of Emacs.  AFAIK, we don't currently have anything of the
sort, though you can always say

    EMACS=/usr/local/bin/emacs-29.4 make check -C test track-changes-tests

That would presumably need to be given a more convenient interface or
people won't really do it, however.

Perhaps some interested party could teach ERT a couple of new tricks
here.
