@jakobbotsch didn't you want to remove the check in #71707 ? 🙂

[jakobbotsch]

Yes. But I have run into some regressions in #71707 that I need to think about how to fix before that can be merged.

[jakobbotsch]

But I will assign to myself, it should give me some motivation to work on fixing that. 😉
