You can still override the layout component similar to extjs3 bun given that there is no fieldLayout, I've overriden Ext.layout.Layout. It's quite similar to molecule man's solution but it's more general. Working for fields used in other containers than forms.

Ext.override(Ext.layout.Layout, {
    renderItem: function(item, target, position) {
      if (item && !item.rendered && item.isFieldLabelable && item.fieldLabel && item.allowBlank == false) {
        item.fieldLabel += ' *';
      }
      this.callOverridden(arguments);
    }
});

This is simpler than your solution but not necesarely better, se example also used in fieldsets here
