"You" is doing all the hard work. Apps should use reliable sessions and transport, almost all the time? No disagree. The exceptions are understood. But don't pretend the substrate is that reliable data stream. "We" have to construct it almost always. We do reliable for you, over UDP. I don't do this stuff any more, but I worked on OSI transport and remote operations service mapped to UDP and other protocols back in the 80s
