Despite having added #11, we still saw during the 1.54 beta promotion that master behavior on a particular test seemingly differed from that observed on the beta channel. In particular, rust-lang/rust#86413 was only able to merge with the pgo-branch-weights test disabled, even though this test worked on master at the same time.
We've also been applying patches to workaround non-working tooling (e.g., RLS) on aarch64 MSVC -- rust-lang/rust@c4aeccd only on beta.
Ideally the beta promotion should be much smoother -- without need to backport patches to make it work. We should figure out how to help make this happen, perhaps by adding another -beta builder like we did to fix #11, though this feels a little wasteful.
