Yay git notes! I've been meaning to dig into building something exactly like this with them, because I hate how reviews and comments are basically a lock-in mechanism. There's a lot of room for building interesting stuff with notes, because they let you attach data to commits (and therefore files, lines, etc) without changing the SHA. E.g. got a question about a change months after it's committed? You can add a note to it, and now everyone can benefit from the Q&A. IMO it has just been missing a killer feature implementation or two, to spread knowledge that it exists and get more tools to expose them. They're invisible on GitHub's UI, for instance.
