Re: [w3c/manifest] Add a unique identifier for a PWA (#586)

> As described above, if a user agent receives a redirect response when fetching a manifest URL, it can choose to replace the app (including its new ID), rather than install the new manifest as a separate application. That way the redirect only has to happen once on the user agent (but the server would need to maintain redirects for old manifest URLs for user agents which haven't updated yet).
This means though that the site can never switch to linking to the new manifest url. Since it would not know if the client still has the old version of the app keyed to the old manifest url. The user agent would probably need to refetch all the existing manifests on the domain first to make sure the IDs are up to date, a process that's likely to be brittle (defunct urls, temporary server errors, etc..).
