Personally, my ideal is to:

 - tag all parking areas with an area
 - tag only public car parks with a node

This means that you can easily see the places you can park
your car because of the car park symbol, but the
"private"[1] car parks for residents in housing estates,
etc, are not marked out so prominently.

I'd prefer the area and node renderings to stay separate, therefore.

See, for example, here:

This multitude of car parks is for residents/visitor use in
a housing estate - it gets messy very quickly when icons are
added automatically (see difference between t at h and mapnik
views).

Another way to look at it is that all car parks are areas
(area) on the ground, but some of them you want to highlight
as a public amenity (node).

[1] "private" in this sense can mean those that are intended
    for residents, even though the public can park there if
    they want
