[dns-operations] Google's name servers compressing names in SRV records

I noticed last night that Google's name servers are compressing names
in SRV records, e.g. "dig -t srv _xmpp-client._tcp.gmail.com
@ns1.google.com".  According to RFC 2782, "[u]nless and until
permitted by future standards action, name compression is not to be
used for this field."

Has there been any standards action permitting this, or are they
violating the specification?  This is causing interoperability
problems for caches that are SRV record agnostic.
