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 objects.
Points with addr:* tags are commonly in use and accepted, there is no
reason why addr:postcode would have to be different. When possible I
also prefer tagging addresses on buildings or building:part but there
are multiple conventions in use (points, points+interpolation, points on
entrances).
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.
Thank you. I've been using your overlays a lot. However, given a choice,
I would much more prefer a periodic, maintained import. Much less prone
to errors, more up to date and easier to merge with buildings, if needed.
