Comment(by strk):

 uhm. now that's a good point.
 So, what's the plan for 3d indices and such ?
 Which gets back to... shouldnt' we define operators of boxes rather than
 geometries ?

 The only reason why I hit this issue was for 2.5d topology, in particular
 the mbr field of face table. I guess I can get away by keeping it 2d no
 topology vertex dimensionality, but wouldn't want to go against the wind
 if gbox
 is introducing smarter boxes.
