flag highway that terminates on amenity=parking

[GerdP]

We have a test WayConnectedToArea that complains when a highway terminates on a closed way tagged e.g. natural=wood or landuse=residential.
I was surprised to find out that this test doesn't complain when the closed way is tagged with amenity=parking.
I think it is a common tagging error. Mappers seem to assume that that a closed way with amenity=parking works similar to a closed way with highway=pedestrian?

A discussion in the mkgmap dev list shows there is no consensus about this:

If we decide that a JOSM treats an amenity=parking like a highway we should change other tests like UnconnectedWays,shouldn't we?

I'd prefer the opposite. amenity=parking is no highway=*. Adding area:highway=service would define it as the area of a highway but still it is no highway. Only highway=service together with area=yes is an highway=*

I even find amenity=parking share segments with highway=* for parking spaces along a road. I like to get a warning for this situation, as well.
