Unfortunately reality is new mappers cut and paste buildings so you end up with multiple buildings with the same address. There are three other problems, maintenance is the first. How do you ensure that new buildings get a code? Second in many parts of Africa the same building gets mapped more than once. Usually the outline that closest fits the building is left but that may not be the one with the address tag and finally how do you prevent someone from changing the tags? Vandalism is not unknown in OSM.
>From a practical point of view an encoded lat and long is a sort of basic works anywhere solution. Where there is better organisation for example in the alpine regions of Europe then more traditional forms of an address are to be preferred.
