People, please quit comparing this to flying. Flying is not something humans or any of the Eorzean human-like races can do. Swimming is. The only issue is breathing. And as far as that is concerned, the "hurdle" for swimming, as aether currents was with flying, would be some sort of explanation for infinite breath underwater, whether it be some aether bullshit, or an item Cid shat out on a Tuesday afternoon.

If it were up to me, I'd have the "swimming expansion" begin with regular breathing, then somewhere probably about 75-80% through the story obtain the means for infinite breath. That way, areas that were inaccessible before due to lack of air could now be explored, much like flying with 3.0.
