Very true. Even if we guarantee that callbacks are fed references in lexicographic order, that would only allow us to stop iterationg when we see an irrelevant one", and still would force us to skip over all the irrelevant ones until we see the first one in scope. It makes perfect sense to give us a way to say "iterate only in this subhierarchy" like this step does. Nice.
