state of Node type registration tool and class generation tool ?

[ruchi goel]

Hi,
  The grffito JCR mapping proposal documents the need for the following :

   *

     The JCR Node Type Registration Tools :

         o

           Registers new JCR node types from an xml file.

         o

           Registers the classes as node types while using the mapping
           model.

   *

     The Class Generation Tools : Generates classes out of given node
     types while using the mapping model to know how the classes should
     be generated.


Are these tools

  1. In the list of good to have ?
  2. In design and development stage ?
  3. In proposed stage ?


Thanks,
ruchi
