Documentation needed for new module-for-acceptance

Before ember v3 we had module-for-acceptance file, in it I could declare default beforeEach and afterEach hooks for all my application tests:

import QUnit from 'qunit';
import { resolve } from 'rsvp';
import startApp from '../helpers/start-app';
import destroyApp from './destroy-app';

export default function(name, options = {}) {
  QUnit.module(name, {
    beforeEach() {
      window.localStorage.clear();
      Object.keys(window.Cookies.get()).forEach((cookieName) => window.Cookies.remove(cookieName));

      this.application = startApp();

      if (options.beforeEach) {
        return options.beforeEach.apply(this, arguments);
      }
    },

    afterEach() {
      window.localStorage.clear();
      Object.keys(window.Cookies.get()).forEach((cookieName) => window.Cookies.remove(cookieName));

      let afterEach = options.afterEach && options.afterEach.apply(this, arguments);
      return resolve(afterEach).then(() => destroyApp(this.application));
    }
  });
}

now we dont have such functionality so I dont know how to extend setupApplicationTest(hooks), with cache clears.

@sbrichards, I was able to accomplish this just now by adding tests/helpers/setup-application-test.js with my previous destroy-app code:

import { setupApplicationTest } from 'ember-qunit';

export default function(hooks) {
  setupApplicationTest(hooks);

  hooks.afterEach(function() {
    localStorage.removeItem('person-token');
    …
  });
}

Then instead of importing setupApplicationTest from ember-qunit in each test file, I import my overridden version.

yes this is not a global module extension, I already used these. The issue is some of my hooks are very repetitive when I write them for every module. module-for-acceptance.js used to replace QUnit module() with predefined beforeEach, afterEach logic. Could we reopen this?
