[OSM-talk] Shared nodes between non-routable objects?

[Serge Wroclawski]

Recently I've found several examples of nodes shared between two
objects in my local neighborhood.

The question is: Is this okay?

If the objects were routable (eg roads), then the answer would be
obvious, but these ways are things like buildings and parking lots,
where the shared nodes are the border between the two.

I see a case for and against them. Since they're not routable, I don't
immediately see a problem. Nodes are simply points, and a point can be
shared between two objects, and so why use extra nodes if they're not
needed?

The other argument is that for simplicity sake, objects should be
discreet if possible. The nodes in the parking lot shouldn't be the
nodes in the building. And if one would want to manipulate one object
(ie redraw the parking lot), they'd need to do a complex manipulation
of making new nodes, then reconstructing the way, etc.

I don't think there's a right/wrong answer here; I'm just curious
about people's opinions.
