I've been wondering if we'll see a number of 3rd-party PWA site wrapper apps for visionOS at launch. Where you can create a rich bookmark for various websites to more easily separate their windows and use them.
I explored this briefly for Widgetsmith but since it would require making the app 17+ (unrestricted web access) and I suspect Safari would get this ability natively at some point soon it never get promoted to a proper feature but would seem like a useful tool for the initial period.

Maybe not in the context of Widgetsmith, but I think there is a place for a good #SiteSpecificBrowser app on all platforms. #FluidApp and #Cromeless were good entry points but are not maintained anymore. #PWA is only halfway there. Individual browser instances is better. And it does not look like Apple will do this well.
