[AUCTeX-devel] Re: CVS repository synchronization for RefTeX

[Richard Stallman]

    Then there might be the problem that RefTeX is not in a releasable
    state at the time an Emacs release is about to happen.

This is exactly why it is bad to maintain parts of Emacs in a separate
repository.  Every such package causes difficulty for Emacs releases.

    What about branching?  IIUC CVS branches can only be created for a
    whole module.  Would it be okay to create a branch for all of Emacs if
    one for RefTeX only were necessary?

Yes, it is ok.
