Nonsense. There's no connection-oriented networking in the classic 
Ethernet, for instance - and IP ran fine on it. It's only the newer 
Ethernet incarnations that installed connection-oriented principles 
below IP, due to operating on point-to-point connections on the physical 
layer. (Which again shows that, as you already mentioned, having 
connection-oriented principles rooted pretty deep in the network stack 
seems to have /some/ benefits.)

You /might/ consider the current route through the internet a kind of 
IP-layer connection, but given that it can change even from packet to 
packet, and the packets can reach the receiver in arbitrary order, I'd 
call that pretty far-fetched.
