Merged as this is almost only a syntax change. Tested locally and all is fine.

The other build failures are unrelated but concerning. Should we open a separate issue to keep track of these?

[SeekingMeaning]

Most of the Big Sur failures are acknowledged in #65000; I'm not sure why llvm and glyr are failing

[iMichka]

glyr is known too: #66450
