If I remember right, the jQuery plugins site was one of the only other open-source repositories powered by the Drupal Project module (drupal.org/project/project) besides drupal.org itself. I think that jQuery might even have been running the Drupal 5 version. The Project module, which they'd have to either fix or dig out of, is a massive chunk of code. Upgrading to Drupal 6 would be painful, and finding people who have the knowledge and desire to hack on the Drupal 5 version would probably be really tough.
