13	* instead of creating per-user autosave revisions depending on post lock and
14	* assigned author.
15	*
16	* Only overrides when autosave_rest_controller_class is not explicitly set,
17	* i.e. when WP_REST_Autosaves_Controller would be used by default. Post types
18	* with their own specialized autosave controller (e.g. templates) are left alone.
19	*
20	* @param array $args Array of arguments for registering a post type.
21	* @return array Modified array of arguments.
