[Bf-committers] RFC: "Continuous integration" branch?

I’m not fan at all of a 'global staging' branch idea, afaik gooseberry
was supposed to be that… What I mean is, I think it will always diverge
one way or the other. We could make per-patch staging branches, but
would add some noise in our git repo…
I really prefer storing such things locally. That way, each dev can
handle things under his responsibility the way he prefers (local
branches of course, but maybe also mere list of patches to apply, or
whatever). "Public" branches should be kept for reasonably big projects,
or sensitive things that need early testing/team work/whatever, imho.
