Think of the HTTP proxies, not just origin servers. Using an HTTP proxy
is often _required_ when sending traffic over an HTTP port. These HTTP
proxies will break all the muxed DNS traffic they will get. Opting them
"in" will be a lot more difficult than opting a specialized origin
server that wants to participate...

And yes, this deployment concern applies to port 443 traffic as well,
unfortunately.
