This may come with its own limitations, though.

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.
