Fair points and a welcome clarification. And even as a non-expert, I did know (just for instance) that Batman was inaugurated in 1939; and by 1940, Robin was already on the scene. So any period of “originalism” was, indeed, quite brief. However, I don’t think this disqualifies the point about going back to first principles — the foundational roots of the character as originally conceived in Detective Comics #27. Of course, this doesn’t mean that “originalism” is the only valid interpretation. But it is a valid interpretation.
