I can live with either of these sentences, but they don't make sense
togther.  If all of the mechanisms will give you the same answer, why
shouldn't I be allowed to send out all the queries at once and take
the one the comes back first?  Or if new ones are supersets of old
ones, prefer the more informative one?

Right, I think the first sentence is a little bit suspect. We may eventually want to make TXT, say, historic such that it still works in the way that -base expected it to work, but with new extensions for DKK that may well change the interpretation
such as giving finer grained ways to assess the signature, etc.
