Despite my personal feelings about CDN tricks and the DNS, I would observe two things. First, if resolvers have expectations about consistency of zones and so on, then they're broken. The DNS has only ever been loosely coherent. You're simply _not allowed_ to make that assumption from any point in the network except inside the authoritative server and, maybe for certain kinds of consistency, in the slaves of the same zone. Second, the Internet is actually working today using those kinds of CDN tricks. Indeed, some of the most important and most successful nodes on the Internet rely very heavily on various DNS tricks, and without them wouldn't be operating. If we are serious about "making the Internet better", surely we ought to have an opinion on how to offer (as well as can be achieved given other strictures) the functionality that is in fact ubiquitous. I realise that you already conceded the point that this particular extension ought to be documented since it has a code point. But it seems to me we ought to be more enthusiastic than resigned in this case, even if we have to hold our collective nose as well. Either those who understand how the DNS works will document what to do, or else people who have no clue will make more "improvements".
