Why not list the 6.x version?

I see from the entry on http://drupal.org/project/Themes there's a link for the 6.x version of this theme, and on your site you list a 6.x-1.0 version for Admire Gray. Looks like it's been out for about six months. It's released under GPL, so it's eligible for listing on drupal.org.

Without a 6.x version checked in at drupal.org, though, it doesn't show up when users filter themes by 6.x compatibility. Why not post one?
