Also the CNAME if you have a cname you don't want any other records with the same name. It ends up being a confusing and ambiguous situation to be if. You are supposed to use the cname to jump the the actual record. but now there is also a MX record here are we supposed to do anything with it?

Indeed, a semi-common footgun that is allowed by BIND and I think many other servers.
