I would not like to see that happen. OSM maps real objects, postcodes 
are not real and only apply as a part of an object's address. They apply 
to buildings (delivery points on buildings really). The postcodes in 
Codepoint Open are centroids derived from a combination of all the 
delivery points that share the postcode so are not at all real-world 

If you want to apply postcodes to addresses you can see the map overlay 
I have produced which you can use in editors as an overlay: 
https://codepoint.raggedred.net/ I will update it again shortly. You can 
also derive postcodes from other open data sources such as FHRS data.
