So, two of the transports you list above (UDP and DTLS) are unreliable; is
reliability not a transport property you expect for HTTP message exchanges?

Of course you can build reliability on top of unreliable transports,
but that seems
to go against the idea of clean layering (since it is usually the app
the recreates
the reliability).  Can you provide some clarification of your thinking here?
