Well, it's working fine for me (maybe something was changed internally?) with the simple patch in bug #1695103 [1] (similar to what you proposed in comment #3).

Nice! I was considering that option, but seeing that
a) they are not fetched by default
b) very few GUI frontends for git support git notes (notably neither GitHub nor GitLab, but also SourceTree and others)
I ruled it out as it would result in almost zero visibility of that information.
