What would be nice is that notes are pushed/pulled automatically with
standard git push/fetch/pull commands. Usually git walks the DAG
starting with the pulled commit or tag and following the parents. With
notes, the reference is reversed, the note pointing to the commit and
not the other way around. So handling this automatically in Git would
be really useful.

The other feature I'd like is that notes are automatically folded in
the log during git rebase (maybe similar to the squash option). If you
rebase, you lose all the notes (though this depends on the workflow,
it may not be needed with published branches).
