Hey Andrew, The most complete "library" is actually the wgctrl-go one from Matt (CC'd). It's complete because it supports all the same interfaces as wg(8) -- Linux Netlink, OpenBSD IOCTL, and x-platform UAPI. The embeddable-wg-library is just for Linux Netlink, but I should maybe refactor that to be more modular. And as you pointed out, the wgnlpy stuff is Netlink also.
If you wanted to start a new cross-platform library, and essentially "clone" Matt's Go library into a pure Python one, I'd certainly welcome that effort and would be happy to help. Jason
