There is kind of a symmetry to it. Get a question that the asker has studied and watch the answerer squirm. Seems like it'd be more fun, and probably more insightful, to take turns... :-)

Also great way to get marked as "that asshole on the interview". People know each other in the industry.

So then you're advocating for an appeasement ritual? Most interviewers would rather feel smart than talk to another person as an equal. More than a few times I've seen candidates disqualified because they made the interviewer feel inadequate. Who exactly is the asshole in that case?

Yes, one only has to proof competency on those topics once- after that to ask - is intentionally embarrassing.
