Changes to macOS and iOS a few versions back removed third party kernel extensions. So, that’s not an issue anymore.

It used to be a huge issue, but thankfully that’s been fixed. I can’t tell you how many times my Mac crashed due to faulty “enterprise” security kexts.

Well, whatever, but maybe you might like to know that it's a protocol specification, not a .ko soley and has been implemented in the user space is several languages. If you're reading every line of kernel source you compile with better knowledge than all of LKML then fair play to you!

There are several things wrong with this - to start with, WireGuard isn’t in the iOS kernel.
