It's presumably going to add relatively few postcodes [as a percentage of the total number of postcodes in the UK], so won't be that much use for anyone wanting to use OSM data for postcode look-ups. Indeed anyone wanting to do that could just as easily use the centroid data directly to map a postcode to a location, and then use that location to do whatever searching they want to do on OSM. There is obviously some advantage in that we'll have more buildings / amenities with properly assigned post-codes. But because of the relatively low benefit (unless I'm missing something) I would say that the community should see good evidence for an extremely low error rate on the import before agreeing that it would be a good thing to do. So what evidence is there for this low error rate? What is the result of my suggestion to look at buildings where there is an existing postcode in OSM and your method would have a postcode to assign to that building? What percentage of those buildings result in a match for the postcodes and what percentage result in disagreement? (Rather than just producing some comparison data and asking others to check it, I would say that the onus is on the importer to come up with the evidence that the import is going to be accurate.) In any case, as Andy says, I think a better use for this data would be an ITO-OSM-Locator-style view where local editors can compare the data with OSM and use it that way to help verify / improve OSM manually.
