yesterday's war = don't bring up that operators are having a real
problem with UDP, and that operators have and will continue to block
it?  Because, i think that is what this thread is about.

i did bring yesterday's war to the IETF RTCWweb group and got the
expected answer

My concern:

Summary IETF response:  The problem i described is already solved by
bcp38, nothing to see here, carry on with UDP
