Can you outline the general purpose of this class too? It seems to basically be
a bridge between the WebKit API and the JS running in the ServiceWorker, which
is exposed through ServiceWorkerGlobalScope?

For example, Is this where the callbacks from onfetch/etc will dispatch out to
chrome?

Yes, that's the current plan. I've added some overview comment here.
