We don't need this for Gecko, and it's hard to implement in that case because there's nowhere obvious to put it (we don't plan to create TSDs for non-dirty nodes, and non-dirty nodes can have dirty children which require the children_to_process atomic). There are various solutions here, but punting is the easiest. We'll need to rethink this if/when we need to do a bottom-up traversal for Gecko.
