Fair enough: a three-branch model with a release branch at the side of
bugfixing and bleeding edge.

This is what I think is confusing: the bugfix branch (be it maint or any
other) should always have the same _unless_ you want to track release
specific bugfixes (which I don't think you do, but you tell me).  If it
changes name at every release, that just begs for a mix-up to happen
when you are preparing for release and someone else tries to do one more
fix.

Why not name it release then and keep maint for fixes?  You could even
install that release branch retro-actively if you want.  BTW, this also
means you need to prepare the release on the hotfix branch, no
fier-upper on the release allowed at all (since you would need to merge
that back).

But as I said before, clone the repo, branch off the 7.7 release or so
and re-trace the following releases via cherry-pick according to that
new development model.  You will quickly learn if what you have to do
feels right and if you commit to that model you will have practised the
moves a few times already.

Another thing that I'd recommend is to not work on the public repo _at
all_ and specifically never push to it, especially not automatically.
The public repo should be "bare" (without a work tree) and any work on
the server should use a clone of that repo, just like anyone else.  If
you prepare the releases on a fresh clone apart from the development
clone, you have a stable base to work from and can nuke with no
consequences if something goes wrong.  Git was designed to make merges
easier, but they are hard and I still botch about every tenth that I try
unless they are really trivial.  Once the release repo is finished, have
it reviewed and then pull from it on the public repo.  The reason is
that it is easy to push from the wrong branch onto the wrong target, but
you really have to try to do that when pulling.  You can be more liberal
with the normal development and bugfixing work on the development repo,
but it would still be a good idea to have commits reviewed and signed
off by another person before they are pulled into public.
