There's no problem. That is exactly what I do.

But as I mentioned, in some cases a minor change to my code can enable users to
keep using it after some Emacs dev change. And so I sometimes make such a change
to help them out, though still with no commitment to keep things synced and
working wrt a moving dev target.

IOW, I do this kind of update only exceptionally, and only if the change is
minor and I expect that the dev code will be fairly stable wrt the change.
