Why had the userpoints.tid field gone from views?

Hello,
in older versions of the User Points module there was 'tid' field declared for 'userpoints' views table. As of current latest version (1.1), this field has gone. But when constructing views it still may be necessary to filter userpoints records by category (my project does that, for example).

So, why not to return this field back by simply returning this piece of code to userpoints.views.inc?

  // Describe the points column of the userpoints table.
  $data['userpoints']['points'] = array(
    'title' => t('!Points', userpoints_translation()),
    'help' => t("A User's current !points.", userpoints_translation()), // The help that appears on the UI,
    'field' => array(
      'handler' => 'views_handler_field_numeric',
      'click sortable' => TRUE,
    ),
    'argument' => array(
      'handler' => 'views_handler_argument_numeric',
      'numeric' => TRUE,
      'name field' => 'points', // display this field in the summary
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_numeric',
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
  );

Thank you!
