title: What is the purpose of helm delete --purge
body: <p>Using helm is super cool, but what is the purpose of using <code>helm delete --purge</code></p>
  
  <p>I can see the <a href="https://github.com/helm/helm/blob/master/docs/helm/helm_delete.md" rel="noreferrer">doc</a> says:<code>remove the release from the store and make its name free for later use</code></p>
  
  <p>So what is the purpose of saving the name and not releasing it with <code>helm delete</code>?</p>
