This would, to be a general purpose thing, need to create a protocol per
datagram. This would be... inefficient. In TCP you have a protocol per
connection. In UDP there are no connections. You might build one on top
of UDP, in which case you would have a protocol-ish object you dispatch
to, but how you determine this object and its lifecycle would be
something you would have to determine.
