not sure if we need postorder now, but need loop all anyway right?

postorder is only used in import/export, which we haven't implemented in python version.

The new one visit the same amount of nodes as the previous one, but is simpler.
It could be further optimized after new node key format, because we can traverse nodes with whatever order, so we can just traverse them ordered by node key with the version as prefix.
