Hide roles from the Access Control table

Would y'all be interested in a feature that hides selected roles from the Access Control table? I created a module for Drupal 5 that does just that and someone in #drupal suggested that it would fit in well with the Utility module. The Drupal 5 version of the module is in my sandbox (http://cvs.drupal.org/viewvc.py/drupal/contributions/sandbox/junyor/acce...). I should be able to update it for Drupal 6 fairly easily if y'all are interested in including it.
