you are right, but there are setups, where the possibility that you can 
not reach the rest of the world is less than the possibility that your 
misconfigured clients/viruses will abuse your bind with thousands of 
queries per seconds for a domain name, which ns are unreachable, and 
your bind will try to follow up many times every such a single packet, 
without any sense.

Have it as an option, will help.
