I'm not sure that's a major concern though. If you receive an MB RRset
and you don't implement that type, or if you do but your impelementation
assumes the rdata won't be compressed and it is, then you could just treat
it as an opaque TYPE7 RRset.  We do have experience with interoperation
between servers that implement different sets of rrtypes.
