I think the real issue is that what should be rendered at highish zoom
is complicated.  For a footway that only goes 20m, having it disappear
fairly soon makes sense.  But a 3 km footway through a forest is far
more important.  Same for driveway, which is not really that inferior to
"service road", but is more important than "parking_aisle".

So to really do this right, I think some notion of characteristic
distance of the way needs to be calculated, and that used in the
suppression decision.
