[dns-operations] Wildcard label as CNAME target seen in the wild

[Mark Andrews]

No it has a bug report. There is a difference. 

Hostnames and aliases are required to be LDH,  RFC 952 which was relaxed slightly be RFC 1123.  DNS is more than just hostnames so what is legal in DNS is not always legal for the consumers of DNS.  The consumer in this case is correctly rejecting the invalid intermediate ALIAS as its job is to enforce hostname rules on data returned from the DNS.
