Making the 6.2 content part of the flying meta makes complete sense in that context. Imagine the rare spawns, the hidden apexis crystal deposits, the treasures, and bonus areas that you'd skip over if you had flying and could just go to do your quest objectives and be done with it.
I'm a supporter of having flying back for convenience and quality of life considerations. I'm also a huge supporter of having to finish the world content for the expansion to have it unlocked. "Here, you've done everything we've wanted you to do, you've seen everything we wanted you to see, enjoy the convenience of flying."
