mess up more than they help, but it is something which can be done. An example of data which doesn't have a real world meaning would be the TIGER TLID. That would be data which isn't crowdsourced editable. Whatever TIGER says the TIGER TLID is, that's what it is. That kind of stuff shouldn't be imported.
TLID can be useful for very narrow situations - I have encountered one in my playing with conflation algorithms. Obviously very far from a general purpose tool, it allows projection of high accuracy updated unnamed road geometry onto the original sloppy sketch. Without a TLID, it would require the mapper to manually delete and create the new one, or spot the general shape and associate the 2 objects.
