It is not like they were telling us "don't add addresses, we can do it 
better". They have done it to workaround two issues, one with OSM data, 
the other with Nominatim itself:

- For a long time we had close to zero coverage of unique postcodes. 
Even now are are at around 16%.

- Nominatim doesn't support searching addr:postcode tags (don't ask me why).

Both are fixable, making the database more useful to everyone, including 
people not using external data.
