Doing this work wouldn't only give us a way to specify which refs we want, but if done correctly would future-proof the protocol in case we want to add any other extensions down the line in a backwards-compatible fashion without having the server first spew all his refs at us.

Anyway, an implementation that allows a client to say "I want X" is simpler than an implementation where a server has to anticipate in advance which X the clients will ask for.

Oh sure. I just wanted to know if you were working on delaying ref advertisement to avoid duplicating efforts. I had the impression you were given your earlier E-Mail, but obviously we had a misunderstanding.
