I would assume that to know how to work with X I need to know how my strengths and weaknesses as Y relate to them—otherwise this is just another way to see the world as 'me vs them'
The interesting part to me is that I don't think a person is necessarily just one type at a time. And there's another list of "these are the great types of developers" and I think people can probably be one or more of those good types and one or more of the bad types at the same time.
I find the Actor theory applicable - in the end, everyone in an org has dominant interests, usually not many.
And the most dangerous are the systems players - because organized groups can take out and dominate any individual. One of the reasons why those playing the system vs the value creators take over in most large organizations.
I think you hit the nail on the head. Personally, I'm really nervous of anything which further deepens "me vs them" dichotomies. They're really unproductive. If you're acting as a leader in any capacity building a product, you have to figure out how to nip these things in the bud before they metastasize like cancers.
I have found myself in a few of them.
