I'll leave it up to you.  But I usually find it pretty easy to maintain
code that works on old versions which making use of new features in
new versions.  And it's perfectly OK to have such backward-compatibility
code in emacs.git.

In contrast I find it painful in the long run to have to manually
propagate patches installed in emacs.git to elpa.git and vice versa
(especially since you can't just `git merge`).
