We can determine the out-most node ("shortNode" with value embedded) by node path.
e.g., paths: [], [1], [1,2], [1,2,3], [1,2,4]
then we can know [1,2,3] is the one of the target node.

That's a good point, the problem is that this is a map and so it forces us to get its keys, sort them and then go over them again and again, like a tree. Probably more efficient if you can make it work, but this is also quite easy to mess up and the code will be way more unreadable. But that's just my intuition, I'll think about it.

actually I think sorting and checking the path lengths is enough to make things more efficient. I'll continue investigating.
Filtering for leaf nodes was missing from ethereum#32388, which means that even the root done was reported, which made little sense for the bloatnet data processing we want to do.
