Safari is compliant. It's behind but compliant. Well, kind of. There are all sorts of minor glitches that only happen on Apple devices. A common complaint is iOS Safari's interpretation of vh units. It might be technically correct (because the spec is sufficiently ambiguous to argue that Apple's choice meets it) but it's still obviously broken for common practical applications that work everywhere else such as attaching content to the bottom of the visible area. The handling of the "notch" on devices that have one is likewise arguably technically correct but obviously broken. So the objections to Safari aren't just about not supporting Google-style PWAs features. Some of them are about other big features too. Support for HTML5 media elements and the backing technologies has been very lacking by modern standards and numerous special cases have been needed over the years only to support Apple clients.
