Searching for GB postcodes on the OSM site works already. The search
system, Nominatim, has extra datasets loaded to improve the search and
one of them already is Codepoint Open. If you search for postcode that
is not currently in a GB address (it's not yet been added possibly
because the buildings it describes have not been created in the database
yet) search still find it and centres the map on the imaginary postcode
centroid. So to make searching work we do not need to import imaginary
postcode centroids to the main OSM database.
