You can use web notifications, and you can compile Objective C to webassembly. You're also able to use apple pay. Everything you've mentioned has a workaround.
I'm really getting at how PWAs are basically something most people wouldn't use, not because they're missing APIs but because they're just a terrible experience and difficult to install and use.
If its Apple that is holding back PWAs so much, its not that they're any successful on Android either.
And then to extend the argument further, "App Clips" or "Instant Apps" aren't much success either from an adoption perspective, despite having full access to the APIs native apps have.
