It seems I misread you, then.

The more I think about it, the more I agree with the MAJOR release
base for our branches, what I still don't quite catch on is your
thinking around the release on new MINOR releases...  you seem to say
that they shouldn't be allowed, at least under certain conditions, or
always, and question is then, what's the actual difference?
