Comment (by DD32):

 It also allows for multiple filters, eg:

 {{{
 add_filter('post_content', 'f1', 10, 2);
 add_filter('post_content', 'f2', 10, 2);

 function f1($content, $attr) { return 'F1' . $content };
 function f2($content, $attr) { return 'F2' . $content };
 }}}
 That would result in 'F1F2' as the gallery, If only $attr was passed, It'd
 be impossible to have multiple filters on it (Which while you may not see
 the need, There are occasions which it could be useful).
