Sure, theoretically, any PWA could possibly be developed as a better native app.
But in the real world people develop apps. If the iOS app developer and designer market declines, then even if theoretically a native app would be better, the best developers and designers will have little to no experience with native and so the best apps will likely be PWAs where the best developers and designers are.
Native only always win if you’re looking at the capability of the platform as the only constraint. In reality, the developer/designer market, money available to develop apps, money and resources available to maintain apps, etc are all additional constraints for real apps, and native apps have significant disadvantages in those other constraints.

That's a pretty huge "if". If the web developer market declines, then native will be better, too.

In my experience, the reality is much more nuanced than that. There are plenty of mobile devs, and many will tell you that they are not slower writing two apps (iOS/Android) than writing one cross-platform one. I don't know a single mobile dev who likes a cross-platform framework better than the native experience, too.
No really, I think cross-platform seems cheaper if you are a manager (and don't really have experience with any of those frameworks) or if you are a web dev (and don't really have experience with mobile frameworks).
