And then what about other countries?  In Taiwan, there's the idea of main road, alley/subroad, then building identifier.  I'm sure other places will have different address formats.  Someone just mentioned that the best solution is to create a geocoder for each "type" of address?  Is that the trajectory of geocoding for OSM?  To have a per-country/region based geocoder?

And, someone mentioned that Nominatim isn't good in the US?  I'm trying to implement some basic geocoding (all US addresses), and that would be somewhat devastating.  Is this actually the case, before I spend time going down this path?
