TCP over WireGuard is unavoidable because that's the whole point of tunneling. But TCP over WireGuard over QUIC just doesn't make any sense, neither from performance nor from security perspective. Not to mention that with every additional tunneling layer you need to reduce the MTU (which is already a very restricted sub-1500 value without tunneling) of all inner tunnels.

Agreed, but that wasn't what I was saying. Read it carefully next time before downvoting.
If the argument is if wireguard is a state machine, well, TCP over wireguard is just fine. And that's exactly what I said.
