Some other collateral changes needed for the above to work properly:
- 430 status code MUST have less priority than any other 4XX response
since such 430 response can only be replied by edge proxies and means "the TCP/TLS connection with the user is closed".
What about the 439 code, i guess we need support in the server for this as well?
Yes. But IMHO it's not so interesting as it would just occur in case the proxy between client and registrar does not support RFC 5626 (and I suppose that both servers would always be provided and configured by the same admin).
