I am unsure about how/which experience of yours made you conclude Service worker as Rube Goldberg machine, as otherwise with just few lines one can write a service worker. Push Notification has its own use case, a user who wants instant stock updates and don't want to install a whole big native app for just this, can simply accept notification from a PWA and starts getting customized notifications. No need to install the PWA itself, juts subscription to notification is required. Regarding push service and its usage for spams, the user has full control to stop those notification any instance. Personally PWA seems to me as the greatest thing that has come out of web, which gives full control in user's hand. User can very easily see what data an app collects and control what data user wants to share.
