The issue isn't about drawing upon some inate power/competency, it's the degree in which it's done.

Holding your breath for longer or lifting a heavier car than you thought possible is enhancing a known capability. Surviving in the vaccum of space and flying aren't known abilities.

I think we see this kind of thing done much better in The Mandalorian where we see Grogu manage to utilize the force in small ways initially (and not always as intended), then building things up over time. That's what we'd expect from someone inexperienced in the force, able to call upon some elements of it when needed, but not pulling off feats someone trained in the force can't do.

Thats why I say Rian had little respect for the franchise. He literally says he wants to subvert expectations, but in many ways he was just breaking existing lore and/or rules of the universe. That's not good writing in my opinion. To subvert expectations you can't just change the rules.

Edit: Spelling/grammer

Listen. There are only a handful of hills I am willing to die on. And one of those hills is that the "rhymes with 'hat hat'" pronunciation is objectively wrong. Like even Lucas could say it and it's wrong. "AyTee-AyTee" is the pronunciation. This is because there are other vehicles in that series, most notably the AT-ST. So what do you call that? The "Aht-EssTee?"

Maybe this isn't the full scene, but it shows her getting blasted into space unconscious, eyes bolt open and she flies through space, then she's on the ship unconscious. So like, I guess maybe technically she was conscious during the flying, but that's still pretty weak.
