Apple has no incentive to make PWA or web apps work natively since they don't get their 30% cut on that.
Steve jobs made it abundantly clear when he blocked Flash on iOS citing battery and security reasons and every developer including myself hailed it as the best thing that could to the internet then; never figuring out the insidiousness of such changes and how it was a priority for Apple to cripple the web browser and keep it crippled to make their App store flourish and get more % cut on apps. They have made billions of dollars doing that and Steve jobs was truly a visionary in this regard.
