> Do users have some other escape hatch to tell PGO "ignore what you think you know about this branch" so that a user who *wants* PGO to lose has some ability to do that other than "don't use PGO"?
Sounds like we need another proposal for [[always_likely]] :)
I understand both pros and cons of PGO having preference. However, whatever solution we stick to, I'd prefer it to be consistent.
