Comment:

 Today it's possible to filter the gallery shortcode attributes via the
 `shortcode_atts_gallery` filter. Example:

 {{{
 add_filter( 'shortcode_atts_gallery', function( $out, $pairs, $atts,
 $shortcode ) {
     $out['include'] = '27'; // change IDs provided in shortcode
     return $out;
 }, 10, 4 );
 }}}

 includes/shortcodes.php#L676-L690

 Also as Callum noted, shortcodes are on the list of components being
 proposed for a form of "maintenance mode", where no new features are
 added. Source: https://make.wordpress.org/core/2025/07/02/proposal-

 I'm going to close this ticket to help clean up Trac, but feel free to
 reopen if you think otherwise.
