It just seems we judge the "local" aspect completely differently. The
point that I don't get is: How to share a branch without sharing a
branch name? You cannot. Of course you may "change the name" during the
push, or during a fetch, and at that point you know both and can map the
description.

Note that I'm not tied to the notes implementation. But versioned branch
descriptions would be nice for several purposes, for example series
cover letters, or descriptions on long lived feature branches. And I
don't see how else to have versioned descriptions.

Also, for transporting descriptions via config, you have to have an
updated git on the server side, whereas anything object/ref based would
work now, right?
