Robin: Yes indeed. If you can find a cutset for the tree, or cluster a manageable set of variables, all is well and good. I suspect this is what happens with most real-life causal models.
But in general, finding a good non-tree method is not just NP-hard but AI-complete. It is the problem of modeling reality itself.
