I think that's a serious misreading of what's happening in Iran.

Air superiority still matters a lot. But the way you establish air superiority is by systematically annihilating the enemy air defenses.

Remember all those Tomahawks, ATCMS, and other PrSMs the US absolutely dumped into Iran until their supplies started to run low? Yeah, you're supposed to use those to kill the enemy's air defence. That's exactly what they're good at. Instead the US just kind of threw them at whatever, including girls schools. Then they threw their aircraft at a still largely functional air defence network and were surprised when they got shot at.

The same thing is happening in Ukraine. Russia wasted their high end cruise missiles blowing up apartment buildings and then sent poorly trained pilots to fly so low and slow that they could be hit by MANPADS.

That's not supposed to be possible. Shoulder mounted anti air is basically useless against a jet fighter flown by a competent pilot (they're meant for killing helicopters). The only reason Ukraine is killing Migs with them is because the Russian pilots are so bad.

Nothing has changed about the importance of air superiority. We're just watching two object lessons in how to completely fuck up getting air superiority.
