Hypothetically, if you're using one of those funky NoSQL-style backends where RRs are looked up in a key-value store directly from a (QNAME, QTYPE) tuple I can see how supporting QTYPE == ANY would be tricky.

The fact that "ANY" exists can put some significant implementation constraints on your system :(
