I agree with dpark - an unstated goal of this proposal was for developers to be able to easily move legacy sites with legacy endpoints to long sessions without needing to update those endpoints or pages.
The service worker approach can effectively intercept requests to any endpoint and perform the re-generation of a short cookie if needed, without needing to change every page on the site or the legacy endpoints.
