When converting a WebForms app with KendoUI controls in it to MVC, I used the MVC wrappers.  One thing that became very apparent is the lack of support for client templates.  For example, a bound column has a ClientTemplate, but no ClientEditorTemplate or ClientHeaderTemplate. Because of this, extra JS code has to be written to manually manipulate different parts of the grid.  Considering the MVC Wrappers render out the same HTML/JavaScript as the pure JavaScript counterpart, it would be EXTREMELY helpful if client templates were made available anywhere a server-side template exists.
