Why Polyfill? I think that this would work if it's loaded before Angular (or whatever library):

Because we need to modify the response, we don't need to polyfill the entire API, just the parts we need.

So I found this package: https://github.com/jpillora/xhook

xhook.before((request) => {
  if (request.url.match('/users')) {
    return { status: 200, data: { a: 1 } }
  }
});

It also has can be easily disabled with xhook.disable()

It does not support fetch() though, but we can use it for v1 just to make things up and running.
