But how many of the 15 million are the results of imports taking the
easy way of using addr:street? Taginfo lists combinations and we
have 2.3 million that also have osak: tags, 0.8 million that also
have kms: tags, then lesser combinations such as uir_adr:ADRESA_KOD,
usar_addr:edit_date, mvdgis:cod_nombre, chicago:building_id and
surrey:addrid and that's only got me to page 5 of 519 of the
combinations.

Then you have all the people who have used addr:street instead of
the relation because it seems the more popular option, perhaps only
because of those imports.
