Hobbling browser engines is a key pillar of app store control. Decent PWA support would be a massive blow to Apple's bottom line.
It's not just that, Apple also gets $20+ billion per year in AdSense revenue from Google for being the default search engine in Safari. A change of even 10% marketshare would cost them billions, and this money is pure profit.

This is the conspiratorial version.
The more likely explanation is that when every app can bundle their own browser engine, we will not see a competition explosion. Instead, Electron apps will come to mobile, with every app shipping its own browser stack.
You can’t tell me Gecko, which has already failed on desktop, will suddenly be popular on mobile. You can easily tell me every app shipping their own Chromium would be very popular with developers.
Is Chrome's PWA support on Android a massive glow to Android Play Store's bottom line?
I don't buy this line, that Safari is intentionally hobbled to prop up the App Store. What's iOS missing for PWA's to be a viable money-maker for companies? Surely there so much money on the line that we would see companies using them. What does Match.com's portfolio of dating apps need to be viable as websites instead?
In reality, when you actually pay attention to Apple's software engineering practices you realise how incredibly cheap and stingy they are. All the apps are so under funded and under developed. Bugs are introduced all over their native platforms all the time and never fixed.
