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.
