100%. PWAs are not a priority for Apple (and shouldn't be for developers) because users don't search for apps in web search engines, they search for them in the App Store.
App store discoverability is very poor. Web discoverability is much easier to manage. It's something you have more control over and can buy easier through marketing via any channel you want. App store pages just don't convert well.
I agree about the installation process (though the user shouldn’t need to fill in any info). The actual user experience when using home screen PWAs can be made to be OK, but there really needs to be a meta tag or whatever to allow an ‘Add to Home Screen’ banner to appear (similar to the way you can link to the App Store if you have a native app).
Open the Share sheet, scroll down, tap "Add to Home Screen," fill in the information, tap Add.
There are simply no users that do this, and it is not an alternative to having a mobile app in the App Store.
