You mean QUIC, no need for HTTP/3 for the distribution.

 From what I understand it's still built on top of TCP. The main 
advantage of QUIC is that you can map messages onto different streams. 
Each stream's messages are ordered but the whole connection is not. 
Streams don't block each other. Different streams may have different 
priorities (we could have a process_flag that indicates this for very 
important processes and the distribution driver would send their 
messages before others).
