Interesting question. Since it is a resource, it makes sense that you can
bind to it. So I'd say, yes. But, I'd understand if servers decided to fail
such a request.

I just gave it a quick look, and it seems like the BIND protocol
specification does not mention lock null resources.

I think this is fine.
