Indeed. Safari, once very forward thinking, now lags behind every major browser in features and compatibility. Apple saw progressive web apps first as a revolutionary feature that could drive iPhone sales, and then second as a revolutionary feature that would eat into their app store revenue.
That‘s a misconception. Apple added the progressive web apps feature to early iphones because people asked to develop custom apps. But rolling out a complete custom app platform is a heavy task so web apps was a very easy target to implement. Maybe the early iOS didnt even have a sandbox to run untrusted apps, who knows.
