Is it anymore feasible to implement WG in an OS-less ("freestanding") environment where something like a TUN interface doesn't exist? Take one such environment, an RTOS, and the popular open source https://www.zephyrproject.org/. It has a full networking implementation but apps typically use BSD sockets (https://docs.zephyrproject.org/latest/reference/networking/sockets.html) or PPP (https://docs.zephyrproject.org/latest/reference/networking/ppp.html) and network management (https://docs.zephyrproject.org/latest/reference/networking/net_mgmt.html) directly. Also, these implementations are very optimized as they typically run on tiny MCUs (~100 Mhz, 256kb ram.)

It's likely our rust implementation well be well-suited for what you
have in mind.
