It is silly but you have to meet customers where they are.

I think the problem is also that PWAs don't have any discoverability, and no standardization. I did some consulting work for a company that had a PWA. They had a 200-line long react component that was intended to determine what modal to show the user depending on what web browser and OS they were using to instruct them how to install PWA depending on the combination of OS and browser.

This is a lot of friction for the dev, and it's not clear to an average user what a PWA is. But they are familiar with, and for better or worse, trust, the App store. If I didn't know what a PWA and a site said "open menu and click on 'install!'" I'd be very wary of following those instructions!

I think Android and iOS should provide some sort of hook between the app store and PWAs before they really start to catch on.
