I will for some things. I have a couple web apps I visit throughout the day and it's nice to have a shortcut on my homescreen, and to not have the address bar taking up space.

Speaking from a technical perspective, adding a PWA to the home screen is useful for recognizing user intent to have a richer experience with an app. Push notifications, adding an app to the share sheet, etc. - things you don't want just any website to do, but might want to permit for a privileged site.

I don't want to install an native app for every restaurants that I visit every 3 month. I want to use PWA instead.
