Recoil uses useMutableSource behind a flag. I thought this was fine because Recoil isn't used in any concurrent roots, so the behavior would be the same, but it turns out that it is used by concurrent roots in a few places. I'm not expecting it to be hard to migrate to useSyncExternalStore, but to de-risk the change I'm going to roll it out gradually with a flag. In the meantime, I've added back the useMutableSource API.
