It's hard to see anything that a DMARC include would do that a CNAME doesn't already
do just as well.  Since the DMARC record has a unique name, you don't run into any
of the problems you do trying to put a CNAME on an MX or A record.

I realize that provisioning systems don't support exotic records, but
CNAMEs are not exotic, and have been around as long as the DNS has.
