It's never been wired up. Only userspace that tried to use it (and didn't actually check whether anything works, but hey it builds) is the -modesetting atomic implementation. And we just shut that up.
If there's anyone else then we need to silently accept this flag no matter what, and find a new one. Because once a flag is tainted, it's lost.
