Author not set on site node creation (and other hosting content types)

Just noticed that all the sites I'm creating are authorless. I'm not sure if this code is new or not, but I think it's caused by this snippet in hosting.module:

  // Remove additional UI added by core modules, that conflict with the hosting UI.
  $node_types = array('site', 'platform', 'server', 'client');
  foreach ($node_types as $type) {
    if ($form_id == $type . '_node_form') {
      unset($form['options']);
      unset($form['menu']);
      unset($form['revision_information']);
      unset($form['author']);
      unset($form['comment_settings']);

      // because these aren't really posts, 'preview' doesnt make sense in this context.
      unset($form['buttons']['preview']);
    }
  }

I think when the author field is unset, drupal won't use the defaults. I've only tested this on site nodes, but I assume the same will happen on all. The attached patch fixes this by setting the uid for the node in the presave nodeapi hook. Not sure if this is the best, or right way to go about this.
