[ emphasizing agreement ]

unless the whole world is using ...  the dns is global.  this discussion
is yet another rinse repeat.  realio truelio, if there is a cname, it
MUST be the only RR at that label.

people with other beliefs are welcome, nae encouraged, to break their
own zones.  i prefer not to communicate with them anyway.
