[Tagging] Use cases: where would a count of all lanes be useful?

Tagging geometry when you can have the geometry as geometric
entities? From a usability perspective that's bad, it's mixing totally 
different mental models. And it's harder to survey/estimate lengths
both on the ground and from the aerials (where available), than
to place a node and split.
