As far as > it is branched from a fairly stable version, What you describe is what I mean by "feature branch". Features branches are a tried and true way to work; I do not mean to say "don't use feature branches". > For the case of bidi, if there's a plan of another big > change in the display engine, the above merit is big. bidi already has a branch or a repository or something. It only needs to be canonized as "accepted in principle" for v24, and given an official URL. My understanding of what Stefan proposed is something different: that as the maintainers decide that some features are important to add, they be merged to the "for v24" branch: bidi with lexbind with .... > By the way, the case of emacs-unicode is very special.

Ben Wing worked out how to have toggle-able buffer formats in 2002 (then disappeared from XEmacs, unfortunately, but the infrastructure is present). I'm not saying it's a good idea, but it's possible.
