That's an abandoned idea.

All of you stupid, read RFC1035

   The difficulty is that the presence of one
   RR type in a cache doesn't convey any information about the other
   because the query which acquired the cached information might have used
   a QTYPE of MF, MD, or MAILA (which matched both).
