Confirming Consensus IETF 74

I agree that this is a fair representation of the consensus at the WG, 
and I agree that it represents a reasonable way forward.

The purpose of confirming the consensus on the list after a physical 
meeting is (as I think of it) to verify that there is no significant 
group of list members who disagree strongly with the consensus reached 
at the WG meeting.

Thus, in this case (but not in very many others), it's reasonable to 
assume that silence is consent.
