Re: [w3c/ServiceWorker] Making a concurrent request for navigations (#920)

In https://codereview.chromium.org/2416843002/ I was made aware that this proposal introduces a nullable promise type into the IDL. I guess `navigationPreload` is supposed to be specced as a `Promise<Response>?`.

We are actually hoping to outlaw that from Web IDL entirely: https://www.w3.org/Bugs/Public/show_bug.cgi?id=25049

Can someone summarize why a nullable promise type is needed? I don't see any IDL in this issue, and I can't even see anyone proposing `navigationPreload` as a promise for Response, much less a nullable one, so maybe there is just some confusion going around.
