[dns-operations] Adding CNAME for the root domain issue

[John R Levine]

> This is not an UI issue at all. It is actually an issue of bending under pressure. “users are always right” is an easy excuse, but never the best. Users do what is possible.

No, users are always wrong.  But they will do what they do, and a sensible 
designer builds designs that users can use in a reasonable way.  When we 
demand that people use long random passwords and change them every week, 
their reasonable response is to write them on sticky note and stick them 
on their screen.  (The security minded stick them under the desk.) 
Blaming them for not following rules that make no sense to them is a 
complete waste of time.

Actually, plenty of other protocols use SRV, notably SIP.  HTTP is just 
special.
