Pre-merge checks is in beta. Report issue. Please join beta or enable it for your project.

I feel like the bar should be fairly low for committing this. The proposal itself will notify those who are interested (agree or disagree) where they can join the discussion.

Many lines are over 80 characters (some people read these in raw rst format). Other than that, it looks good to me.
