I didn't say overkill doesn't work, did I :-)? I think that until we delineate the true trade-offs between natural keys and artificial keys, if any, you should design your schemas/schemata as you deem best. If it turns out that there are situations where each has advantages then those situations should determine the correctness of the schema.
