Re: How to "backport" a patch from master to emacs-28?

Yes, that can be done, indeed.  But please mark it as a "backport".
Or use `git cherry-pick` which should label it similarly.  This should
make sure that the next time we merge from emacs-28 back to `master`,
`gitmerge.el` can automatically skip it to avoid spurious conflicts.

Note also that AFAIK there is currently no plan for an Emacs-28.3
(we're instead planning to cut the `emacs-29` branch soon, tho there'll
still be many months before the Emacs-29.1 release).
