As someone who normally has that "different view", I support a new RRTYPE

requires DNS-SRV-followed-by-HTTP. I think a new RRTYPE that keeps the
DNS lookup entirely in the DNS protocol far outweighs reusing SRV but
requiring HTTP on both sides.

"in this case" as in the draft under discussion? If so, I don't don't 
understand your position. The protocols/services being referenced by the draft 
are HTTP protocols, so it is always going to be SRV-followed-by-HTTP. What is 
more, simply getting a generic host/path is not sufficient for client 
configuration - additional steps are required to find the principal resource 
of the user for whom the client is setting up an "account" (as described in 
the draft).

Sorry, I wasn't clear. My "in this case" was "how does the IETF want to handle 
the case of getting a resource from the DNS", not the CalDAV/CardDAV case. It 
may be fine that the CalDAV/CardDAV API include HTTP, but I would hope that the 
IETF could settle on one DNS-specific method that all apps could use.
