Of course, forwarding can actually use *more* bandwidth if the 
forwarders are overloaded/slow/unreliable (thus causing frequent retries 
from the client). This seems to be fairly common, unfortunately, because 
forwarding doesn't scale very well and ISP's frequently fail to 
provision adequately for the query traffic they end up having to deal with.

I agree that one should not have an ironclad "forward" or "don't 
forward" rule. However, I think "don't forward" is a reasonable default 
(assuming one has a choice at all) unless one has specific reason to 
think that forwarding will derive some technical or economic benefit.
