I don't really want to repeat the discussion we had in 

https://github.com/openstreetmap/osm2pgsql/pull/684

My original idea stands: It would be good to have an idea how far the

has reduced a lot it would make sense to actually remove them in the 
standard map relatively fast before the numbers increase again.
