Correct me if I am wrong, but if the root is part of the inventory, then it can
be moved (by a topological delta).  It has also the further implication that the
inventory is a tree, not simply a forest, and that all topological deltas must
preserve that invariant.

I have not thought about this much at all, but I get the uneasy feeling that it
could make things slightly more complicated (unless, you, in one way or another,
"special case" the root).
