Quite a strange idea. The source IP spoofing problem mentioned in the draft has a known "solution" - making ISPs check source addresses before routing. I get it ain't very easy, but stopping using UDP wouldn't be easier anyway. The proposal is especially strange when you consider that almost nobody uses UDP, TCP (ok, let's be honest: HTTP) is the "default" protocol for everything. Those who do use UDP, usually have quite a good grasp of what it is and when it should be used (VoIP, video broadcasting, DNS, uTP).
