You choose whatever browser you want for any PWA you happen to want to use. The OS will put a small badge on the icon which shows the browser responsible for running it. If things go south you know which browser to blame. You can install multiple versions of the app using different browsers and compare them, then only keep the one which you like best. Freedom of choice is a good thing - for users.
