I'm confused by what your point is, then. You want evidence of an abstraction that exists in the minds of experienced developers? That's like asking for evidence of humor or love. We accept these things as real because of shared experiences, not because of concrete evidence.
My point is that the paper has no point, the article on the paper is a stretch, and none of this is relevant in any way except creating chatter.
It's useless from the research perspective. But it is a cup-holder for marketing something.
I already laid this out very clearly in my first comment.
