Re: [ServiceWorker] Proposal: Optimized No-Fetch Service Workers (#718)

Ah I think we'll have to check the _list of event types to handle_ even before a service worker starts running, the property itself should be an internal slot of a service worker instead of the environment settings object. Anyway, the idea is just get the set of event types from the initial script eval and use that to check whether we should not actually run a worker just falling back to network.
