Let's not confuse addresses as raw nodes with no addresses.

That's a bit like me saying a healthy meal is better than junk food, and
the response being that junk food is better than no food. It's not what I'm

The issues with address points are:

1. They're often in the wrong places. You just don't know it until you have
building footprints to compare it to.

2. There's not a whole lot of data about addresses being updated

3. (as was brought up in the NYC building point discussion) There's no code
that I'm aware of that correctly parses address points inside building
polyogons in such a way that non-addressed POIs get the address attributes.

4. If geolocation is the issue (which it seems to be), then we could feed
that data to the geolocator directly, rather than placing it in OSM.
