A good time to mention that the P2P Yggdrasil network uses QUIC/TLS selfsigned certs but then runs its own encryption over that. You can add as many peers as desired, and the network will automatically choose the best path (latency). So no multi-pathing but gets around the issue of changing IP addresses/network locations. Plus, it's able to do multicast to find peers in your LAN without having a centralized control server. I'm actually getting better speeds than WireGuard over my LAN - but this is a stable link. Once you start sending the yggdrasil packets over long unstable links you may start to get into funky issues like TCP in TCP head of line blocking, but they try to mitigate this by having huge MTU sizes and packet dropping algorithms.

I'm currently working on creating a managed Yggdrasil relay node service. A feature I hope they implement is QUIC multistream support.
