I like this idea, but it does not have to be an error, just a grouping.
Here's why: we are all volunteers, with conflicting priorities in our lives. If we have the time to write a bio, we can look at the list. Our days are full of interruptions; work, family, friends,hobbies,tax returns, you name it. Plus, we are learning the art AND science of genealogy, using the tools we can afford.
So this would help us -- we can chip away at the list as we have time..
