title: Why Does ClaimsPrincipal Have an AddIdentity Method But No RemoveIdentity Method?
body: <p>The ClaimsPrincipal class, has the ability to contain multiple ClaimsIdentitites as follows:</p>
  
  <pre><code>public ClaimsPrincipal(IEnumerable&lt;ClaimsIdentity&gt; identities)
  </code></pre>
  
  <p>ClaimsPrincipal has an add method AddIdentity to add a claims identity to this claims principal. Why is there no RemoveIdentity method?</p>
