-Remove `Querier`, `Route` and `LegacyQuerier` from the app module interface. This removes and fully deprecates all legacy queriers. All modules no longer support the REST API previously known as the LCD, and the `sdk.Msg#Route` method won't be used anymore.
+Support for the `AppModule` `Querier`, `Route` and `LegacyQuerier` methods has been entirely removed from the `AppModule`

+Most other existing `AppModule` methods have been moved to extension interfaces in preparation for the migration
