If you edit a road, a new one would be created and would point to its
invalidated ancestor. Recursively chasing previous ID pointers, you
would eventually have an object without an ancestor. ID of that object
would also be permanent ID of the successor objects. This will also
solve road split problems as multiple objects can point to the same
