I think there are some aspects of WireGuard that are, I guess, technically interesting. The massive baggage of Captain WireGuard® believing he has creative control over other people's projects is a non-starter for me. An illumos community member put up with him doing PR reviews on a port of the Go version for quite a long time, until his majesty pulled the rug out one day.

I am lead to believe that if we decided to add native support to illumos, for example, that we would probably not be allowed to provide configuration tools that fit alongside all our other native IP interface and tunnel configuration, because that's "not WireGuard".

The motivation to engage is, at this point, extremely low. If we do ever decide to implement it, I expect it will end up being compatible at the protocol level but called something different to avoid the Kool-Aid guy busting through the wall as a result.
