Fair enough.

One problem I see is that there are hundreds of such local labels in the Lake District alone. If all of these were added to OSM, then they would overwhelm the map, and interfere with the more important data of features on the ground. That said, I suppose it is the responsibility of the displaying tool to determine what should be shown at what zoom level.

Furthermore, imo, the Langdale Pikes is a collection of hills/tops, and not an area – and certainly not a natural feature – so laying down a border for it is inappropriate on a map.
