The slides don't mention this, but he did touch on having layered designs so the 5% remains possible. However, the primarily exposed api shouldn't get sacrificed for said features. By conceding on a feature that makes the API less usable, you sacrifice more than not having it in the first place (confusion, complexity). Even the GH Issue linked shows a possible solution to the issue using urllib2, which is just a layer down.
