[Reviewers] Heads up: new accept process is live

[Matt Mackall]

The new accept process we discussed at the sprint is now up and running. And to
make sure it gets tested, I'm going to focus on tooling rather than review for a
while. So to keep patches flowing, you'll want to dig into this sooner rather
than later.
