Comment:

 Yes, this is something that was left as a todo in the implementation of
 Menus in the Customizer for 4.3, as can be seen here:
 https://core.trac.wordpress.org/browser/tags/4.3/src/wp-includes/class-wp-
 customize-setting.php#L687

 The `wp_setup_nav_menu_item()` function sets an `_invalid` property if the
 object that the item refers to is gone (i.e. obsolete). So this needs to
 be exposed as a read-only property of the `nav_menu_item` setting,
 probably in [https://core.trac.wordpress.org/browser/tags/4.3/src/wp-
 includes/class-wp-customize-setting.php#L856
 WP_Customize_Nav_Menu_Item_Setting::value()]
