 Why not? Geographic coordinates can be optional but are important if 
 you want to create a network graph with pre-determined positions on a 
 geographic map or on a background image (imagine a floorplan).

 By adding them so they would be optional we'd also maintain backward 
 compatibility.

 There's no need to reinvent a GeoJSON collection: 
 http://wiki.geojson.org/GeoJSON_draft_version_6#GeometryCollection

 We need a network graph that has also GeoJSON coordinates, if we don't 
 offer a standard way to do this developers will again reinvent their own 
 incompatible way.
