Which can be dealt with entirely at the HTTP/S layer.

People are using CNAME for 

	site -> hosting server

this include "www.example.net CNAME example.net".
 
We need to support 

	site alias -> site { -> hosting server }

		 CNAME    NEW-TYPE

Additionally people are too lazy to add records for each virtual
service in the DNS so they use "* CNAME server" which makes using
SRV hard as it requires prepended labels.

To prevent breaking existing clients that use CNAME like NEW-TYPE
client would look for NEW-TYPE and only re-write the URL there is
a CNAME and a NEW-TYPE returned.

The CNAME would be replace by NEW-TYPE + addresses records to
help with the transition.

This is very much like the introduction of MX records.  At
some point you stop putting in address records.
