qtype in lookup, and DNSPacket::qtype, are rarely the same. Asking a backend for a specific Qtype, in the current PowerDNS backend interface design, would cause it to miss out on information - most importantly the difference between 'no records for this name+type' and 'name does not exist'.

Perhaps this will change in the future, but don't hold your breath. And even if it does change, you will still be required to handle all queries we can throw at your backend!
