Chaining CNAMEs is a violation according to RFCs.

It works, but it is unsupported, and you can only blame yourself when it doesn't.

Maybe I'm misremembering RFC 1034, but a CNAME chain only violates a "should", and later in that RFC it says that software "should not" fail to handle chains, so even if you take a "should" as gospel, the "should not" should be equally gospel, making CNAME chains supported (although not advised.)
