 This may be intentional. But consider the following
 {{{
 $query = new WP_Query(array('fields' => 'ids'));
 if ($query->have_posts() || $query->post_count || $query->post ||
 $query->current_post != -1) {
    //do something
 }
 }}}

 The code that sets all these properties is never fired when getting the
 posts, regardless of what is returned.
 The same happens for `array('fields' => 'id=>parent')`;

 Is this intentional? I can see reasons on both sides of this.

 Perhaps at the very least, the 'the_posts' filter needs to be run when
 these arguments are passed
