Hmmm... we can but I personally much prefer for_each_*() iterators over callback based ones. It's just much easier to share states across an iteration and follow the logic. walk_tg_tree_from() does have the benefit of being able to combine pre and post visits in the same walk, which doesn't seem to have any user at the moment.
