And no, it was a simple one-and-done gag in the typical Giffen style. Personally, though... I'd love to see someone at Marvel find a way to respond by indicating that the JSA's refusal to talk to Joe McCarthy and subsequent going-underground is canon in 616, too... making this a "split" point between the Marvel and DCUs.
Never happen, but it'd be entertaining as all hell if they did.
