The declarative nature should be used to turn instance loaded from FXML into managed beans (inject other contextual instances). For now they shouldn't become contextual instances themselves (they cannot be injected into other beans).

If there is a use case that shows they should become contextual instances, then this use case should be documented and the impacts should be analysed.
