I don't intend to land this, I just noticed that the FTL failures started in this repo on a commit that was an engine roll, which makes me ever so slightly suspicious that it could be the case that there is an actual failure. So I want to see if the tests pass on a revert of the roll, and I don't know how to run these FTL tests without making CI do it 🙂
