It's been nearly a decade, and we're still talking about PWAs being the next big thing. Mozilla/Firefox has killed them off for good [0], and Safari support is tepid at best. It was ultimately just another push by Google a la AMP to corner the browser market some more, and the rest of the vendors are fed up with it. Devs by and large never bought into it because they are objectively inferior to native, while the tiny number of niche use cases where they do make sense have (rightfully) just avoided the complexity and remained as normal web apps.
