They actually have pretty good documentation, and really thought about their data model. They have a total of 20 tables with foreign keys between them. Their is a many-to-many relationship between addresses and points on the map. That is a building can have multiple addresses, and 1 address can have multiple buildings. An address can also have subaddresses. And each table has an ID in it. Having the IDs in osm would make it a lot easier to compare the databases. Having 2 databases you can compare is very handy to check for mistakes. You can of course compare their old database against a newer and try to import that, but I have a feeling that that is going to give you more manual work in the long end. I think it's important to try automate things. I really see no good reason not to add those IDs at this point. I don't see the harm in them. I can only see them being useful.
