Any more innovation on using a VPN on a router?

OpenWRT is the top shelf router firmware for privacy & security. It is pretty feature-complete At the router level, a single wireguard tunnel effectively hides all internet traffic from any adversaries between your LAN and the VPN server. Your traffic is private from the ISP, and your IP is private from the endpoint webserver Why do you imply that this single wireguard config is insufficient? What do you think would be gained by a phone-like VPN config app at the router level?
