I did briefly consider something like that: particlarly using areas.
But relations are more general. There are situations where the
areas are only accessible for portions of the boundary.

But I haven't thought any of this through. More importantly, I have
not implemented a router. People familiar with routing algorithms
and their practical problems really need to drive this sort of
thing.
