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.
