Re: [w3c/ServiceWorker] Registering service workers for unique origins? (#1437)

To try to workaround this limitation, I've setup a domain that serves the same content on every subdomain you access (this way, the served up pages have a unique origin). These subdomains are only used once by a client and a service worker is registered for them.

However I do not know if this will cause perf issue for browsers in practice. What will happen as the number of service workers builds up as we keep accessing new subdomains? [I've asked about this on StackOverflow](https://stackoverflow.com/questions/57014830/do-i-need-to-clean-up-service-workers-that-will-only-be-used-once). I think I may be able to call `unregister` on the service worker inside `window.onwillunload` but am not sure, and I don't know if this is even something to worry about
