Admin 2 and Drupal 7 accessibility

Is there a roadmap for the Admin 2 Rubik combination for Drupal 7 given Drupal 7 is introducing accessibility enhancements? I ask because I am looking at the opportunity for visually impaired people to take over part or most of the administration activities on a site, including managing users. If the Admin 2 Rubik combination is not headed in that direction, is there a plan in Drupal 7 to work with one of the new themes included with Drupal 7?

Genesis is the most accessibly of the current Drupal 6 base themes. If there is not a roadmap for accessibility improvements through theme changes or a plan to work with a new theme, I will test with a theme based on Genesis.

I have not found a documentation page for Admin 2. If there is a page on drupal.org, perhaps we could start a child page on Admin 2 and accessible themes.
