Address interpolation should be just a preliminary mapping, since it works well only if addresses are equally distributed along the way. But if buildings or entrances are not regular this won't work.
I agree that it could be used for initial mapping, and interpolation makes it "work" in some fashion -- at the very least, one gets close enough to the area you want to.
That's slightly better than having no mapped addresses, or mapping individual address POIs, without interpolation.
I agree except for one thing: interpolation is way better than having no address at all. Even if it's not precise, at least the user can have some routing.
