I propose to not modify ways by default and to remove the way-id of
ways that are modified during extraction.
What should a tool care if the way references node-ids that it has
no nodes for because they are outside the bounding-box? It has to ignore
The removal of the ID is because this is no longer the way with
that ID but a new and artificially created way that contains a part
of the original one.
