+Two: You can't put a pending response into a Cache, so you have to do your own coordination to prevent a cache stampede.
+
+One: The storage management and intended use cases make it seem not to be a cache at all. From all I've read about Cache, data stored in is treated as preciously as IndexedDB. The browser will not help you clean out unused entries. It's just storage.
