So I will release rc1 with this issue, but remind me - if it hasn't
had any traction next week and the radio silence continues, I'll just
revert it all.

since clearly nothing seems to be happening on this front, and summer
vacations are only going to get worse.

But we'll give it another week. In August huge chunks of Europe will
go on vacation.
