Neither do I but for a completely different reason.

The CNAME problem here is that you use a CNAME to point your web server at 
a third party host but you want to publish your own CAA, not the host's 
CAA.

Hypothetically, you might want to do the same thing with DNAME, but every 
DNAME I've ever seen other than AS112 aliases two name trees where the 
corresponding names are (or at least are supposed to be) under the same 
control.
