You don't want to use QUIC for this.
QUIC is designed to handle loss, and its not meant to be ultra low latency.
QUIC is designed to be used over IP, not on raw ethernet.
There is somewhat of a method to do it this way, especially as its designed to pipe data directly into silicon.
also "the giants of UDP" seems a bit off. UDP is the under developed step child of IP, completely outshined by TCP.
