title: Is @Html.Sitecore().VisitorIdentification() required with Sitecore 8 MVC?
body: <p>Is the following call to <code>VistorIndentification()</code> still required within Sitecore 8 MVC layouts / views?</p>
  
  <pre class="lang-csharp prettyprint-override"><code>@using Sitecore.Mvc.Analytics.Extensions
  @Html.Sitecore().VisitorIdentification()
  </code></pre>
  
  <p>Even without it, page visits appeared to be tracked in Tracker.Current.Contact.System.VisitCount and within the Experience Profile information.</p>
  
  <p>What feature or tracking ability is dependant on this?</p>
