function flag_flag_type_info_alter in Flag 7.3

    // Only add flag support for entities that don't yet have them, and which
    // are non-config entities.
    if (!isset($definitions[$entity_type]) && empty($entity_info['configuration'])) {

      // We deliberately exclude taxonomy vocabularies from the list of
      // supported entity types because they aren't fieldable or directly
      // viewable, which makes them impossible to flag.
