I was also under the impression that they were mathematical centroids of the postcode area but the user guide [1] indeed says: "The point is given the coordinates of the nearest delivery point to the calculated mean position of the delivery points within the postcode unit." (Although this may not be true for all entries - the PQI will provide that info.) So I guess it would technically be possible to use Code-Point Open to add at least one address location to OSM for most postcodes. I'm still uneasy about doing this automatically though.
