I added this comment to the PR:

If x86_64-apple-darwin is a Tier 1 platform, then this must be as well.

We realistically can't as we simply don't have the CI for arch64-apple-darwin based on the definition of tier 1. Otherwise we would all have to run every PR against the buildbot fleet just to test against Apple Silicon.

As of today, nearly all Macs being manufactured by Apple are of this architecture (i.e. Apple Silicon) and Apple has made clear that the few remaining legacy Intel-based Macs still being offered will be replaced in the near future (likely by the end of 2022). So, eventually x86_64-apple-darwin will fade in importance as older Macs are retired but that will take many years.

Yep, and my hope is we will have CI that can run on Apple Silicon at some point which will let us promote the platform, but until then it's not at the same level as the x64 support.
