I really hope that mainstream support for OpenVPN DCO will make it more popular than WireGuard.
I understand that WireGuard got popular because it was kernel-mode and thus fast.
But it's a pain. Trying to find a settings mismatch is annoying. A broken connection can appear up.
Auto-configuring clients is just not there.
OpenVPN has it all built-in. And with DCO, it's fast.
