We'll always have relationships on top of (and independent of) the tree. I think we shouldn't underestimate what the tree gives us. I.e. in small fraction of cases the tree is maybe a hindrance. But if that hindrance doesn't go away but multiplies without the tree, our hindrance is likely coming from the complexity of our problem, rather than from the tree.
