Re: [whatwg/fetch] Add a speculative flag to `Request` as well as related processing (#881)

Sure. In general though, it seems rather brittle for a page to try optimizing the loading of a cross-origin page that might change any minute. Also, if the subresource is already in the cache (say a JS library that is needed for all pages of the prefetched origin), that might actually slow things down to prefetch it if the subresource is already in the cache and prefetch is not allowed to look at the cache.
We can probably start with something simple that solve some of the main use cases and improve upon it.
