Is this a sufficient check in the case of notes? Is it possible that we
re-balanced the fanout of the notes tree and got a different tree sha1,
even though there is nothing interesting to commit?

I didn't check, but I can imagine you can drop the parse_tree here. We
should know the object sha1 once the commit is parsed.
