They are not allowed to give their browser an advantage under the DMA. If you take a look at BrowserEngineKit and BrowserKit there is a significant API surface area they offer for third-party browser engines. They must have been building this for some time. It's really detailed, down to allowing developers to implement their own JIT! [1] they have custom UI components replacing their standard scroll views with ones that better support nested scrollable DOM elements. It's a staggering amount of engineering effort I can totally believe that there is not enough time to re-think and re-architect how to implement push notifications, local storage and whatever other perks PWAs get for non-Safari third-party browser engines running as "apps." They may have lots of money and engineers, but throwing more of them at this problem is not going to build a well designed, thoroughly tested, and secure implementation any faster [1]: https://developer.apple.com/documentation/browserenginekit/protecting-code-compiled-just-in-time?language=objc https://developer.apple.com/documentation/browserenginekit/p...
