Exactly. Netgate has long said that they won't touch it until it's production-ready; they keep pointing to the warning messages in WireGuard saying that it's beta and when the time is right, they'll consider it.

I'm happy they're being cautious. The inclusion in the Linux kernel is perhaps (to Netgate) a sign that things are headed in the right direction.

As far as FreeBSD, all that exists today is a userspace package (AFAIK). Again, I'm hoping someone sees this as a step forward and will start working on the FreeBSD port.

I'm glad to see progress and hoping for more of it!

Userspace already has a package https://www.freshports.org/net/wireguard/
