title: Is Modernizr really needed if you're not using the feature detection?
body: <p>I keep jumping into projects where Modernizr is located in the head, but it isn't being used (at least for feature detection). Now, I love Modernizr, I use it frequently for feature detection and fallbacks on projects that require it; however, the last three projects I've come into it's been sitting in the head without any of the feature detection classes being called. These projects are using vanilla javascript <s>and/or do not require jQuery polyfills at all.</s> <sup>1</sup> That being said... if you're not using the feature detection <s>and really don't need to load a jQuery library</s> <sup>2</sup>, is Modernizr really doing anything aside from making an addition HTTP request and resource to load?</p>
  
  <p>I'm not strong enough with jQuery/javascript to understand if it's affecting anything else under the hood.</p>

  <p><strong>Edit</strong></p>
  
  <p><sup>1</sup> &amp; <sup>2</sup> &mdash; Modernizr is javascript and doesn't require the jQuery library (which makes me wonder why the jQuery library is being loaded also, at least in these cases).</p>
  
  <p><em>Modernizr.min</em> with only <code>#-shiv-cssclasses-load</code> is 7.57 KB whereas <em>html5shiv.min</em> is only 3 KB.</p>
