Hello, Only seeing this note now.

Drawing as amenity=parking_space and not amenity=parking was a deliberate choice due to the situation:
- These areas cannot be distinguished from the rest of the parking (e.g. they don’t have a different number nor owner), so they don’t form another parking.
- The surface is different from the alleys and the hedges are visually nudging drivers at parking very orderly, so they form parking spaces, even if the spots are not individually marked.

The wiki page for parking_space is confusing, because it starts with saying it’s used “to map a single parking space on a parking lot”, but in the table, it says it’s “for defining an area that contains 1 to n parking spaces.”

So, in my views, the correct tagging is to draw a single parking_space for several cars to park and not add a parking inside a parking.
