I make no claims that anycast is definitively safe for protocols and

Really? That's a big change.
Really? There has been text to that effect in the draft since -00.
For example, there are people using anycast to distribute services
using very long-held sessions (e.g. internet radio, HTTP) with great
success, and to ignore their experience and success would be idiotic
and arbitrary.
There are no such http services using stateful anycast (though this is
the first I've heard of internet radio being anycast---I'd have to
question what protocol he means. I think RTP streams may be stateless,
but I'm not certain). The http protocol is definitely stateful,
however.

etc, etc. I think I've said enough in this thread, now; if there are
innocent bystanders who would like more clarification of these issues
they are more than welcome to drop me a note directly.
