Would be amazing to clarify the path forward for the auth and pwa modules, aka. if nuxt-pwa-module is going to be the official PWA module or if there will be a new one (it looks like Elk is not using it), and also if there is already an experimental repo for the auth module somewhere or if there will be something new. 🙏🏽

Very glad to see migration path addressed! Wish you the best in new role!
