Yeah, I think this would be a nice thing to add to v2. I've considered
adding a way to push symrefs (that is, update the head on the remote
side), but that would be a bit trickier. Still, there's no reason the
fetch side couldn't learn a "symref" capability in the meantime.
I don't see a need for this in v0, since all versions of Git that
support this will also support v2. I think it's okay if other clients
have to add support for v2 before they get the cool new features.
