Same here. Also, in my mind, wireguard just works. I tried setting up OpenVPN one time and gave up. Wireguard was a breath of fresh air. Generated some QR codes for my mobile devices, rsynced some .conf files to my machines and I was good to go.
Calling something "plain old" in no way implies that it's old.
In my mind wireguard was still the new kid on the block.
Technology moves so fast.
