No, this is about storing some meta-info about a branch, somewhat similarly how
you can store meta-info about a commit in a note.

Not to a commit, but to a branch. I mean I know a branch is just a reference to
a specific commit, but in this case the mapping would be from the branch's
_name_ to the note object.
