This would be the same. But the target market here is people who use remote services. For example with saucelabs, tests are slow because you send each request from your computer to saucelabs, which then goes to your site. With this, the tests run on Lambda (which is super cheap) and they do requests directly to your server.
Other things we want to do include creating more API methods, like fillIn (which would take an object and fill in a form using the object keys as selectors and submit) and allow for direct access to the document easily. When we have firefox and chrome, we'll be able to do this quite fast, and without typing async/await in your test function.
