These kinds of features are like solutions looking for problems. Is this a real problem people have, that they are getting everything done but they can't figure out what to do enough that they'll write out the whole thing to get suggested tasks?
I think it can definitely help overcome the "mental block" that we (I?) face sometimes when staring at a task list. If something is too hazily defined, even an incorrect breakdown of the task can help me spur into action.
