Considering the 'derived data', the damage may be more than just few insignificant nodes. If someone uncontactable creates a node that later gets used as crossing point of three major roads, their tiny contribution could lead to deletion of all three roads cause of derived data (no matter how many of these three roads were drawn by the man who created the node). Disagreement from (or unsuccessful attempts to contact) one person that made "cosmetic" changes (like changing from highway=minor to highway=residential) to many streets in london in early days of this project could lead easily to deleting (or reverting to ancient version) half of downtown London for example.
