- I think it's doing the Zen 'platform' a disservice. It's a bland theme and not a particularly exciting example of Zen's sub themeability.
- It surely must be an extra burden for the Zen maintainer.
- No real harm done if provided as a seperate download I think? Maaaaybe you can even find another maintainer for it.
- It's just an extra theme in my Drupal's theme list I would rather not have to remove everytime I update Zen.
