Wish they would do this on iOS (and allow a custom install button). They recently removed shared Caches between serviceworkers in Safari and the PWA on iOS, requiring to relogin after every PWA "install" :(

As for your (2) point, I think cookies is the only thing that should be copied. LocalStorage or IndexedDB could result in inconsistwncies and breakage (PWA and Website code can version missmatch).
