As a CDN operator this proposal looks valuable to me, in a long lived connection context (e.g. HTTP etc) quickly moving clients off the anycast address onto a server specific address provides a reliable means for machines to stop advertising the anycast address when they become busy(loaded) but still continue to serve existing connections.

As Christian has pointed out the option to also use MIGRATE later in the connection is also an interesting concept with value, but that is definitely a different issue.
