AppController class in the skeleton says it is "safe to be deleted", but doing so causes errors similar to Fatal error: Uncaught RuntimeException: Named route does not exist for name: index in /home/strike/Frosting/UF5-native/vendor/slim/slim/Slim/Routing/RouteCollector.php

/, /legal, /about, and /privacy are the affected routes.

Most full sites will want to provide their own pages here, but dependent sprinkles should be able to use the defaults without including or overriding AppController.
