The shallow tree is only computed once, and then published over tf. So
every tf listener can efficiently compute transformations between
links. If we publish the more natural tree, then every single tf
listener would have to do extra computations to chain links together.

I'm not sure I understand what you mean. Tf doesn't allow us to
publish the same tree twice.
