I get that Apple shouldn't be allowed to dictate which features belong on the web, but you're just letting Google to it instead if you opt to use Chrome.
Maybe I don't care about PWAs (which I don't), maybe I don't feel like the majority of APIs introduced lately belongs in the browser. There's very little of what you should be able to do on the web that you could not do 10 years ago. Yes, flexbox is awesome, let's have that, so is the dialog tag. WebGL, Blutooth, USB, device memory, battery status... No, the browser doesn't need to support that.
