Apologies, this is not an "issue" per se, more like a question and I did not see any other place it can go (e.g., "Discussions").
The way I interpret the documentation, routers cannot see the data that they are shuttling. First of all, am I correct in this?
If that is correct, then you have a huge difference from plain wireguard (though I don't know if this is true for tools like tailscale and netbird).
My suggestion/request is that you mention this in the README, even if briefly, to make things clear.
thanks!
