Prior to #42152, some of these were too weakly ordered, now many are too strongly ordered. But slowly we get closer to our goal. This adds a checker that prohibits reading or writing to an atomic without explicitly specifying the memory ordering. In principle, that also makes it much closer to our Julia atomics model.
