Hi mobilarte, thanks for the head's up – I did not know about that. But I still think it is wrong to tag bigger parking lots such as https://www.openstreetmap.org/way/347220342/history or https://www.openstreetmap.org/way/1137898951/history as street-side parking, which is why put parking=surface back on. Instead of changing the tag, the solution then would be to add ways leading to these parking lots, wouldn't it?
