The problem is rather that PWAs would prove a viable path for universal cross-platform applications, taking away the gatekeeper role the OS-vendors have.
Paradoxically PWA-support is also part of the "we're no gatekeeper" narrative, so it's in the OS-vendor interest to keep it maintained as a hampered alternative to native apps.
No it can't. The web will never support what's necessary for parity with native apps. Imagine trying to implement Liquid Glass in CSS.
Second (even though it's completely beside the point), especially Liquid Glass could be implemented in PWA, because it's a rendering effect the OS could put on top of appropriately tagged elements of the application. And voila, the same webapp could render in Liquid Glass in IOS26 and in less-gaudy Liquid Glass in IOS28, and meanwhile in no Liquid Glass at all on devices that don't have it...
Android accomplishes this by allowing devices to connect to private app stores and repos, which enable companies to issue their own apps on their own terms. As Apple plays hard ball on this front, the only way is to use a PWA.

Install and discoverability is still hidden. Push is gated behind install. Safari’s scroll bugs haven’t been fixed despite us extensively documenting them, emailing to Safari’s leadership and raising them every year as the number one bug.
The number one thing we’ve asked for is third party browser engines on iOS.
What goalposts do you think have moved?
