This pull request has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you add the label WIP, I will leave it alone unless WIP is removed ... forever!

I'm about to GA change that re-orders and collapses status changes (#72570). As far as I understand that was the thing blocking landing this PR.
