Based on the node IDs, I'd venture a guess that this is because some
of the nodes (the ones without a source tag) were added later (and
quite possibly from a different source).

It's wasteful, but then, without changes to the API, it's hard to see
how to provide the same information with less waste:  Not all nodes on
a way are necessarily from the same source.
