It&#x27;s not just ES6&#x2F;7 transpilation though... there are a lot of ES6 features that are in node, and modern browsers, so not everything needs to be translated all the time... let alone more advanced options like flow and jsx (more than just for react, but mercury and others).<p>That&#x27;s why the change, I do think they pulled the gun a bit soon though, but many would have jumped to it just the same.
