Epic 😄  It's good to have that to refer folks to if they want to use ES modules _today_ and also want to avoid a potential double-download. Long-term, is a more official mechanism for detecting support reasonable to add to the service worker specification?

Actually, since [ES modules in dedicated workers](https://chromestatus.com/feature/5761300827209728) are already supported in Chrome and Safari, how do developers using them deal with what I'm assuming is a similar issue? Perhaps a way of feature-detecting support needs to be done on the `WorkerGlobalScope` level, to address that use case as well?
