That's how Emacs development used to work until several years ago.
Since then, we have made the feature freeze period on master much
shorter, and the release branch fork sooner, because there was
considerable pressure from contributors who didn't like the long

Which of course is anathema in Emacs development.  In fact, I don't
even think it could work in principle for Emacs, because of the number
of distinct areas of expertise which a single individual has no hope
of mastering to be an efficient gatekeeper.

People don't like too many feature branches, even if they are public,
because many times they want more than one feature in their hottest
latest Emacs.
