Has Google Talk implemented XEP-0079?

Google Talk has implemented XMPP (jabber portocol) but has it implemented XEP-0079 too?

XEP-0079 is an XMPP extention about "Advanced Message Processing".

No.

We can use XEP-0030 (Service Discovery) to ask the server at talk.google.com what it features it provides.

XEP-0079 specifies a <feature> of http://jabber.org/protocol/amp but, as we can see from the request/response below, the gmail.com service does not include this feature in its response.

To amplify Christopher's answer, not only does Google not implement AMP, there are few others who do, since it doesn't solve enough of the problem. For something hop-by-hop, consider XEP-0198: Stream Management, which also provides quick reconnect.
