This allows queries to reach the Internet when the forwarder is down.  The
current behaviour is explicitly designed to prevent this.  Yes, this requires
people to think about what they are trying to achieve.

"forward first;" is optimisation "forward only;" is grafting of namespace / server
reachability.

Note "forward" is almost always the wrong way to graft on namespace but somehow
this is what people do rather than slaving the top of the private namespace.
