Wireguard is _really_ simple in that sense though. If you're not doing anything complicated it's very easy to set up & maintain, and basically just works.
You can also buy quite a few routers now that have it built in, so you literally just tick a checkbox, then scan a QR code/copy a file to each client device, done.
My ISP-provided router (Free, in France) has WG built-in. But other than performance being abysmal, its main pain point is not supporting subnet routing.
So if all you want is to connect your phone / laptop while away to the local home network, it's fine. If you want to run a tunnel between two locations with multiple IPs on the remote side, you're SoL.
