I think air unblockables will shut down a lot of airdash approaches. But as for jump cancel stuff, it's not like every air unblockable is fast enough / has head invincibilty. Besides the stuff we're already used to seeing (Ragna 6A, Carl 6A, etc.) we probably won't see a lot more air unblockable moves being used to stuff jump ins.
So yeah, I agree with FlyingVe
