[gen220]

You're right, I was referring to git-notes and they aren't suitable as plumbing for code review :)

I was meaning to point out that we've developed plumbing for objects with "weaker" guarantees than source code, which can still be attached to refs. To me, this is indicative that the maintainers are willing to accept patches on things that are outside the "core mission" of versioning source code, and might mean that they're open to the idea of accepting a well-architected code review feature.

Although, you're also right, in that there's still a lot of plumbing to make sure that authors can only edit their own comments, and that sort of thing. The more I think about it, there's a lot of work to be done and it isn't easy.

But, if you made a proposal, I think git-notes is precedent for them accepting your contributions. :)
