This is a part of #2717 Some settings didn't get getters because - They are transient parse settings (e.g. ignore errors) - They get propagated to args and should be checked there `is_allow_hyphen_values_set` is a curious case. In some cases, we only check the app and not an arg. This seems suspicious.
