 we can use like this

 {{{
 function hwl_home_pagesize( $query ) {
         $query->query_vars['posts_per_page'] = 1;
         return;
 } add_action('pre_get_posts', 'hwl_home_pagesize', 1);
 }}}

 But this will be like a global function that will apply the same settings
 to all loops, not good. Why not just update "posts_per_page" option with
 "1"?

 This is a bug 100%
