The core foundation of OpenWRT is very solid. It needs items that make using and maintaining OpenWRT devices easier. A way to have centralized management of multiple devices (why do I have to manually update my SSID on every AP?). Make it easy to update (like Attended Sysupgrade). Make common 'extras' easy: setup a Wireguard VPN server, connect your network/wifi to a WG VPN, use DNS over HTTPS.
