But there's a difference between "not being published" and not existing. Unpublished information is still available to some group of people, stored on disks etc. It could be accidentally or deliberately released. Given the amount of confidential information that does get inappropriately released I would expect this information to, at some point, be seen by people who shouldn't have access to it. Better that the files don't exist in the first place. Maybe it could be a probablistic correlation set at a level which would require a number of votes to obtain sufficient certainty.
