Glad to help.

Keep in mind that anti-circumvention is a tricky problem that can't be
solved in the application layer alone. We're talking about an
application (VPN) that really needs a datagram-based transport (UDP)
to work correctly, but we have a censor which is willing and able to:

- Inspect and modify packets at the network level (blocking by subnets and IPs)
- Inspect and modify datagrams and streams at the transport level (TCP
resets, UDP black holes)
- Use MITM attacks to downgrade crypto (various TLS attacks)

Unless/until encrypted datagram-based traffic becomes a large and
economically crucial part of Internet traffic (perhaps via WebRTC
calling?) national censors can and will just shut it down entirely.
