Other than in the article, the only other instance I found of the term was from this event at Columbia University, [0] at which the co-authors were both openers. So the term seems to be specific to them and pretty new. Still, in the OP article, the sidebar does solicit readers to submit their candidates and it hints that the list might be published, so something to keep an eye out for.
