Yes, for multiple reasons. TCP is ossified and typically lives in the OS, 
because of NAT the only options for protocols that work are TCP and UDP, 
so if you want to move your "transmission stack" to userspace, your only 
choice is UDP. So enter things like QUIC and others that are mux:ed stream 
protocols over UDP, which can then live in userland on all major operating 
systems.

This is not ideal, but it's not strange that this is happening. The only 
way to innovate as an application/protocol developer is to use UDP.
