You're mistaken. They've explicitly stated several times that they're going to introduce new spells and abilities through the Gift system, which you even acknowledged in
an earlier post.
Again, I do not think that widening the gap between casuals and hardcores benefits anyone. There already aren't enough people logging in to play with. We don't need them amplifying this by disqualifying everyone that doesn't play 20 hours a week from current content. There just aren't that many of us anymore.
And yes, I'm aware that they've said these rewards are just designed to be an unnecessary boon to hardcores who don't need the game to be any easier. That's just not how it works, though. We'll end up with difficulty creep making them required to land spells on D fights. A BLM that has spent 55 JPs on Magic Accuracy has 21 more MAcc than one that has no JPs thanks to Gifts. They can hem and haw about how unnecessary Gifts are for current content, but 21 MAcc is an NQ elemental staff. That's not insignificant.
