I agree with Pieren, and would like to add that relations like these are a
problem when you try to download a small bounding box, and one of those
nodes gets in the way, and now you have to download all the nodes in that
relation. There's no need for that.
But there is one advantage with those relations, and that is protection
against newbies. Newbies can delete a tag from a node because of some their
strange reason, but they don't know how to remove a node from a relation.
There should be tools that mimic that.
