If the command is still useful to a handful of people (some subset of 
CVS/RSC users, apparently), and it doesn't take effort to maintain it, 
it doesn't seem helpful to deprecate it.

Unlike the key binding.

As Juri said, the new branch commands are not ready yet.

His patch was to prepare the users to this prefix being used for branch 
commands in the next Emacs version. You didn't like the proposed method, 
that's okay.

Let's deprecate the binding in Emacs 28, so it can be used for branch 
commands in Emacs 29.
