I disagree, it does hurt.
If we say you're allowed to use CNAMEs to point to DMARC records,
people are to say uh oh, is there something special here? What about
DKIM records? what about SPF records? how about SPF includes? or SPF
redirects?
Really, there is nothing to say here, so let's not say it.
+1, I don't understand what needs to be clarified here. If I ask for a TXT
record at a given name, I expect to get one back (or a non-success code).
It really doesn't matter to DMARC whether that process traversed a CNAME
record in the process. (Or if it does matter, I've yet to see a reason
why.)
+1, people who know DNS can derive the possibility to use CNAME on their own.
Those who don't are better off not trying it.
Best
Ale
