Okay, checked in with the designer, who mentioned that adding that badge would also require a preference to turn the badge off. (Some folks just don't care about reviewing at all.) Instead, we ask folks to work reviewing into their workflow.

Designer handles this by adding a weekly-repeating "review projects" action, which insures that the task shows up as a due item, with a badge.

(Awesome question, by the way. Thanks!)
