Oh, I agree with that. And a name error is cacheable which in this context surely illustrates that it does not represent a failure to send a query or receive a response.

I suppose there's an element of this that depends on the intent and purpose of the query which is not necessarily evident. A query that is sent in order to test an ACL and elicits a REFUSED response might be positive, if your goal is to confirm that the query is blocked. I appreciate that's almost certainly not the intention from the perspective of unbound or its administrator.
