title: body-parser - extended option (qs vs querystring)
body: <p>In the current version of <a href="https://github.com/expressjs/body-parser">body-parser</a>, the <code>extended</code> option when using <code>bodyParser.urlencoded()</code> is now required. In the README, it explains:</p>
  
  <blockquote>
    <p>The extended option allows to choose between parsing the URL-encoded data with the querystring library (when false) or the qs library (when true).</p>
    
    <p>[...]</p>
    
    <p>Defaults to true, but using the default has been deprecated. Please research into the difference between qs and querystring and choose the appropriate setting.</p>
  </blockquote>
  
  <p>I couldn't find any helpful or specific information on this. I only found a deprecated <a href="https://github.com/tj/node-querystring">node-querystring</a>.</p>
  
  <p>Should this option just always be true?</p>
