No, just saying "unnecessary" is not enough to clarify of why you think individual driveways for a residential houses or other buildings/premises should not be added to osm. There are over 8 million objects tagged with service=driveway in U.S. alone. Driveways mapping is a vaild geographic features.

To avoid the clutter map when you edit, you should use filter/hide features to hide or showing only certain type of map object, or if you use JOSM, you can use object filter or using overpass to download only certain type of map objects. Avoid clutter maps should not be a solely rationale to remove something vaild map objects.
