He had no idea that 584mm was an old size that is being pushed again by the marketers as something new.

Some 700c bikes are sold with couplers. A Co-Motion Americano owner I talked to several years ago said that the 700c wheel was too big to fit in the case flat but that it did fit with a slight angle. I think he removed the tires first.

I would not be surprised if there are a bunch of new 584mm bikes sold with couplers in a few years.

But the big danger that I am more worried about is if the airlines switch to a smaller size criteria than 62 inch. I think it was a year or two ago that some European airlines were pushing a new smaller size standard for carryons that would exclude virtually all of the ones currently sold, but too much consumer outrage stopped their attempts at that time.
