I'm not familiar with the details of implementing a PWA and how much it's tied to Chrome specifics (that would certainly be bad), but I generally disagree with you. I feel like way too many companies are making native apps just for the sake of users being able to install them and have that icon on the home screen. Most of the time the app doesn't require any native-only functionalities, it could function as web app just fine, so it's a bunch of unnecessary overhead. And mobile platform owners love this as the growing ecosystem means more lock-in. PWAs seem to be a nice middle ground solution to this problem IMHO.
