Given that it doesn't seem to be a protocol violation, I'd suggest this: For instance, some authoritative name servers embedded in load balancers reply properly to A queries but send REFUSED to NS queries. This behavior causes a variety of problems, such as invalid negative answers, that are so severe that it is unreasonable to expect clients to interoperate with them reliably and so there is no point in trying to work around them.
