It's odd that they mention working with Christian McDonald and not Jason A. Donenfeld or Matt Dunwoodie. The module they reference appears to be https://www.freshports.org/net/wireguard-kmod/ which itself came from the work the latter two did here https://git.zx2c4.com/wireguard-freebsd/log/

And indeed just three days ago the work was announced on the wireguard list https://lists.zx2c4.com/pipermail/wireguard/2021-May/006711....
