Markus, you are not the only one, I am also skeptical about the criteria used. For me the main problem is perhaps the misunderstanding that the "external identifier" label creates, actually what I was expecting was something more like "external references", a place where to put all the external sources to wikidata in one place. But we'll see how it goes.

Cheers,
Micru

Give it another 2 to 3 weeks and it'll get there. More and more editors
are exposed to the separation in the UI now and start noticing the ones
that intuitively should be moved into the identifier section.

Ok, let's see what happens. I am not saying that the other criteria applied now in the discussions are bad. It's just another use of the datatype than I would have expected.
