No, QUIC runs over UDP which runs over IP. QUIC replaces the TCP sessions that a web
browser uses but the device is still doing all of the other IP stuff that it does.
I could imagine that the connection ID might slightly increase the load on a NAT since a device
might be hopping back and forth between networks, e.g. mobile and wifi, and be considered a new NAT
client each time it does.
