Echoing Christian's and Thomas' comments. 

The early-handoff of clients to a specific address could be a useful capability for deployments. In addtion to anycast, this could also be beneficial for load balanced deployments that use ECMP.

The compromise with the TLS extension is that relocation chaining would not be supported (e.g. a service on one anycast IP, directs to another anycast IP, that directs to a non-anycast IP). A MIGRATE frame could deal with this, along with a multitude of other more complex deployments.
