Comment:

 Ignoring requests for `p=0` seems like the expected behaviour to me, it's
 not a valid value for the parameter and thus isn't a single/singular
 request.

 If you wish to avoid the default WP_Query query, you can use the
 `posts_pre_query` filter (see #36687) - code below isn't tested
 {{{
 add_filter( 'posts_pre_query', function( $val, $wp_query ) {
   if ( $wp_query->is_main_query() ) {
       return false; // any non-null value will cancel the request. Can
 also return an array of Post objects.
   }
   return $val;
 }, 10, 2 );
 }}}
