Ya ya yawm TAG!

I'm requesting a TAG review of ModuleServiceWorker.

Chromium supports three types of workers: Dedicated Workers, Shared Workers, and Service Workers. Importing ES modules has been implemented and shipped for Dedicated Workers, but not for Service Workers. We'd like to launch importing ES modules for service workers, since Service Workers are the foundation of PWAs (Progressive Web Apps) and should support importing ES modules to provide the new PWA features.
