The existing through_route proposal may not be perfect but IMHO is a
good base. It will need weeding through to keep it on-topic. 

This is how I see the scope of the discussion (just to get the ball
rolling, feel free to shoot): 

1) it has to be about junctions, not about individual ways (it's not
about warning of sharp bends in a continuous road) 

2) it has to be about aspects which cannot (reliably) be derived from
the geometry alone (see point 1 above) 

3) it must cover factors which affect the way the route to be driven is
explained to the user ("keep left" vs. "take the exit", "follow the road
to the right" vs. "turn right" etc etc) 

4) it *may* cover factors which affect the way the router chooses its
optimum route (e.g. time penalties for a "give way")
