We have to_next_step and to_next_val. We should have to_prev_step and to_prev_val.
They can be default implementations only, for now.
We ought to have benchmarks for them too.
I don't see a great need for to_prev_k_path + descend_last_k_path personally, so I'd rather not add them unless there is demand from a downstream project. I'm not against it, I just think it's probably superfluous.
