Keeping an id tag does give the advantage that the issuing agency can see if we made changes to it. I really think that OSM can work side by side with government agencies to improve both of our databases. Right now we are mostly just a user of the data. But as we improve and refine the data, ours becomes better. For example, this gives fire departments better house locations so they can improve their data.
What is their test to see if we (OSM?) have made changes? What if an OSM user corrects the location, or moves it near a better access entrance, but doesn't touch the ID? In any case, I would think the government agency's best query would be "Give me any address object modified since {last synchronization date}."
I'll agree with Jason's observation that external IDs in OSM data tend to discourage corrections and additional contribution by new mappers.
