I'm not sure. Currently I would delete it. Not to please the renderers, but as 
I see it as redundant data.

I do POIs and my tool currently only can do nodes. If parking lots are 
replaced by areas, I need to fix my tool.

OSM is wiki style. If someone comes along and refines an area, it may simply 
happen that the node disappears as soon the area is created. I agree that 
anyone can put data into the db, but it's not there for eternity but to be 
modified. And modification also means deletion.

Seconded.

Best regards,
