The point is that for when part of a road belongs to a route, you'll
either need to:
* split the ways at the start and end point of that route for the road
and at the ways in between to the relation
* or we'll have to make a new segment relation with that part, and add
that one to the route relation.
So that's what I mean with the extra layer of segment relations.
