 // (windows, dedicated workers, or shared workers), and 2) those for hosting a
 // running service worker.
 //
 // For client providers, there is a provider per document or a worker and the
 // lifetime of this object is tied to the lifetime of its document or the worker
 // in the renderer process. This class holds service worker state that is scoped
 // to an individual document or a worker.
 //
 // For providers hosting a running service worker, this class will observe
 // resource loads made directly by the service worker.

Can ServiceWorkerProviderHost just take a ServiceWorkerProviderHostInfo as an
argument, and use ServiceWorkerProviderHostInfo as a member? This would help
documentation since all these variables are defined in SWProviderHostInfo.

Done.
