I have not looked at the actual patch, but does it allow you to set up its own channels to listen to ?
For example if I'd want to set up a server to listen to incoming connections over QUIC [1] - a protocol which create a connection over UDP and allows clients to move to new IP addresses (among other things) then would the current extensibility proposal cover this ? Maybe a correct approach would be to just start up a separate "postmaster" to listen to a different protocol ? [1] https://en.wikipedia.org/wiki/QUIC Cheers Hannu
