Migrate from ComponentColumn to widgetcolumn

In Ext 4, we use componentcolumn (http://ift.tt/1z3GbvD) to render Ext component in a grid cell.

In Ext 5, the built-in widgetcolumn have the same abaility to do so.

This is an example of ComponentColumn:

Code:

{
  dataIndex: 'age',
  xtype: 'componentcolumn',
  renderer: function(value, m, record) {
    if (value < 30) {
      return {
        xtype: 'myWidget1';
      };
    } else {
      return {
        xtype: 'myWidget2';
      };
    }
  }
}

This is an example of widgetcolumn :

Code:

{
  xtype: 'widgetcolumn',
  widget: {
    xtype: 'container',
  },
  onWidgetAttach: function(widget, record) {


    var items = [];
    if (record.get('age') < 30) {
      items.push({
        xtype: 'myWidget1'
      })
    } else {
      items.push({
        xtype: 'myWidget2'
      })
    }  
    widget.removeAll();
    widget.add(items);
  }
}

Question:

componentcolumn can determine which xtype to render on renderer function (run time) while widgetcolumn must assign a static xtype at compile time.

In this case, when using widgetcolumn, it create a container which consist of a widget.

When using componentcolumn, it create the widget directly. (fewer layers of components)

So my question is: can widgetcolumn determine which xtype to render at run time just like componentcolumn?
