The change to guix-emacs.el is pretty impactful here since that affects
all the emacs packages including emacs-minimal I think.
If I've understood your comment correctly, that does seem pretty
wasteful since those rebuilds because of the changed emacs-minimal won't
have any affect since it's version 28 and not 29, right? I think
applying this change to just emacs-next would have been possible.
