Import complete:
Since the intention is to be capable of provided accurate address data to first responders, error on the side of leaving an address point rather than removing it, is given when there is uncertainty if an addressable object exists on-the-ground. To clarify this, the address data source is authoritive. Meaning, any address could absolutely be dispatched as a 911 address. When an address is assigned to an open field or parcel of land, where no signs of construction are taking place, it is often removed.

Data Merge Workflow
Conflation
Using JOSM, with the conflation and mapwithai plugin. This preserves the existing nodes or buildings of currently mapped POIs and structures. If a single address is assigned to a building, it is merged with the building. If multiple addresses or units are assigned to a building, they are left as nodes on the building. If the addr:unit is the only differentiator, the building is tagged with the address number only.
