Keeping the nat_ref seems like the right thing to do, indeed, otherwise
merging future updates from GeoBase may turn out to be very painful.
But having so many ways seems a bit problematic to me (although such
segmentation is sometimes needed anyway, e.g. when a street changes its
onewayness). Couldn't we merge the segments into a single way and then
keep a list of NIDs in nat_ref?
In any case, thanks for your effort, it looks like a good start.
