I'm really not a DData expert but it's seems to me that Daan has invested a 
lot in good design and efficiency.  So I would like to see the DData modules 
as the standard modules under Data, too.

By the way, is there already a mechanism for marking deprecated code?  Will 
deprecated code be removed some time or will it pollute the libraries until 
the end of time?
