As far as I can tell, they're mostly after compatibility with their
existing userspace stuff. Otherwise, if they were going back to the
drawing board, they could just make openvpn userspace set up xfrm or
wg tunnels to achieve basically the same design. And actually, the
xfrm approach kind of makes a lot of sense for what they're doing; it
was designed for that type of split-daemon tunneling design.
