Ok, let’s try it and see what happens. We can always adjust as we go

Most other projects do however cherry-pick into their releases (that’s
also what linux distributions do when they add patches to their packages).
I still feel that this would make releasing easier, and I’m not sure the
few duplicated commit would be a real issue in practice. Finding out
whether something is part of a certain release could e.g. just as well be
done on the gerrit tag instead of the git sha1.

I think we’re through the merge hazzle with stable now, so I’d keep that
branch until 5.3.0. Once we have 5.3.0 out, let’s aim for renaming stable
to 5.3 and move over to that. We should probably also retroactively create
the 5.0 - 5.2 branches so we have something consistent.
