* once `actorFor` is removed you can only `watch` things you know for real, at which point this change must have been reverted
* if we do not do this change, then we must remove a wildcard-`watched` upon reception of a `Terminated` even though it does not match by ActorRef
* if the aforementioned strategy leaves a program broken, then my intuition tells me that it was broken before

This leads me conclusion that this change should not be done.
