Why do you think it's preferable to return a referral, for a query 
that's in a non-whitelisted domain, than it is to send back a REFUSED 
response, which is what happens in a more typical restricted-query 
configuration?

If the client could do something useful with a referral, it almost 
certainly wouldn't have been sending a recursive query in the first place.
