You were there and I wasn't, but I find this statement a bit surprising.
Certainly the original Cerf/Kahn paper clearly states TCP operates
between HOSTS, with GATEWAYS doing the relaying.
Also, I note that IP's fragmentation model requires a source address.
(Or perhaps, better said, would have been extremely difficult to do
without either a source address or a unique, destination-created, nonce
that was given to the source and placed in each datagram).
