Good point. It is always optional, so if we want to add it later, that's
no problem. I'll drop it if no one objects.

Yes. That was changed later and the new APIs reflect that. It will not be
done atomically on the server, but that's no problem, since we can just
ignore not locked errors. That's a non-error in this situation.

And a pesimization when the lock token is defunct, in which case we need
to unlock, get-lock, unlock. Breaking ones own valid lock should be rare.
