Does anyone know if this protocol uses QUIC's RFC 9221 extension in order to eliminate overhead when tunnelling UDP over QUIC? According to their blog post, TrustTunnel does somehow avoid that overhead, but the actual protocol specification doesn't mention anything of that sort.

No, but it's a very good point, we'll add it to the backlog

Excellent, thanks for the quick response! Are there any plans to add support for full-cone NAT as well, in order to improve compatibility with some games?
