At low level is not related to WireGuard in any way. The wintun project only exposes a virtual network interface to Windows systems, a clean and proper signed windows driver. That side project to Wireguard was created because the native windows virtual interface is too basic for "advanced vpns" and the former windows TUN driver (OpenVPN side project TUN driver for windows) used by everyone was clunky and old.

YG uses it own crypto and routing, wintun is used here only to expose the virtual network interface on Windows.

I see, so there's no real integration between the projects besides the incidental TUN server. It seems like YG would benefit from using WG as a primitive for point-to-point encrypted comms between nodes, and build the spanning tree system on top of it.
