It might, yes.  But that's a poor reason to give an authoritative
answer that a name which does exist instead does not.  Such resolvers
are broken under 6761 anyway, and shouldn't be making such a request.
But lying about the answer is not in keeping with 6761.  There remains
some controversy about what the right answer would be, given some
interpretations of REFUSED.
