title: Why ExtJS4 Store class doesn't have a property/function to fetch store model?
body: <p>I really don't understand why model is bound to <code>proxy</code> and not to <code>store</code>, so if I need a model for the store I have to do something like this:</p>
  
  <pre><code>var m = store.getProxy().getModel();
  </code></pre>
  
  <p>Is there any reason for Ext.data.AbstractStore to has no getModel() method?</p>
