I would agree with that. Unfortunately people keep importing the external ids in the "hope" that they will be useful in the future, but not only are they not useful, but they confuse so many mappers who don't know whether to remove them, keep them, or maintain them when splitting objects etc. I'm not sure what the solution is, but I would like to hear from anyone who has used the ids for the generally stated purpose of updating an import. Otherwise, perhaps we should update the import guidance to suggest that it's not worth importing ids in the first place.
