We do need to realize what this means and be all fine with it.

It means that if someone who is not RM directly commits to the release branch, the commit
will be reverted.
And that from the beginning of the branching…

IMHO, I think this would be a good step but I don’t think it goes far enough.

This still uses a paradigm where a release is made from a release branch that was started
from an unstable development branch.
Hence you still need *extensive* QA.

If we truly want to release faster, we need to release from the same QA’d branch time after
time….a release needs to be based on a previous release

Basically, we need a rolling release cycle. That will have the added benefit to not leave
releases behind and have to focus on backporting.
