It does change behavior. The previous behavior looked up the note OID,
then tried to read it, and if it was missing just pretended that there had
not been a note.
I'm not quite sure whether we should keep that behavior, as it is unclear
in which scenarios it would be desirable to paper over missing objects.
In GitGitGadget, I am a heavy user of notes and it wouldn't do any good to
have this behavior: It would lose information.
And even in scenarios where the `notes` ref is fetch shallowly, I would
expect all of the actual notes blobs to be present, and I would _want_ the
`git note edit ...` command to error out when that blob is not found.
Does that reasoning make sense to you?
Ciao,
Johannes
