Yeah, that pretty much sums up their arguments. The bit about reliable delivery is true, and I wish it would get fixed. Some steps have been taken such as the stanza acking proposal and a JEP that allows entities to keep sending messages until they're acked.
AMPQ is a little different from XMPP. With AMPQ a server consists of a number of publish-subscribe channels, whereas current XMPP servers allow entities to connect as a node (the part before the @). An XMPP server that is like an AMPQ server would most likely take the form of an implementation of JEP-0060 (pub/sub) that only allowed server to server connections.
It's also debatable and testable if their binary protocol would have any speed advantages over an XML protocol like XMPP.
