I'm confused: Does format-patch keep it or strip it as you say above?

Anyways, notes survive rebase etc., and at format-patch time you can
decide whether you want to include them or not (with my patch).

The only difficulty would be sharing notes in a push-pull workflow (for
lack of tool support, though we do have merge support).
