Then your purchases and stuff are lost too, I guess as WebXR matures though maybe there will be some great apps you can just pay directly for on the web, but I feel like if rumors of Apple making a headset they'll just skip WebXR and force the app store... I know other headsets including the Oculus supports WebXR but sorta feels like it's a conflict of interest to their own stores to me so wonder how much more advanced it'll get.
