I think it is a good opportunity to establish guidelines and process so
that we don't end up in this state in future where one needs to lock down
the branch to make it stable. From that p.o.v. discussion on this thread
about establishing a process for lock down probably doesn't add much value.
My personal opinion for this instance at least is that it is good that it
was locked down. I tend to forget things and not having the access to
commit helped follow the process automatically :-).

This is again my personal opinion. We don't need to merge patches in any
branch unless we need to make an immediate release with that patch. For
example if there is a security issue reported we *must* make a release with
the fix immediately so it makes sense to merge it and do the release.
