If those are the extent of complaints, then I think Safari's doing just fine. That's nothing like the next IE, and shows that PWA still have their own problems regardless of Apple.
I worked through the IE days and Safari definitely has a IE feeling that you can't shake off.
IE had a lot of browser features which officially were there but in practice didn't fully work.
I had issues with forms, zIndex, SVGs, backgrounds and localStorage with Safari. All of which I consider basic browser features which should always work.
Of course it's not as bad as IE but Safari is clearly lagging very far behind Chrome and Firefox
It's interesting how the "Apple can do no wrong" shareholders and "I will hate on PWAs no matter what" types, curiously converge and keep regurgitating the same talking points that have been addressed ad nauseam, even in this thread. Every technology has its "own problems" regardless of Apple, but it certainly doesn't help when Apple, being one of the biggest companies in the world, persistently engages in its sabotage.
