Well, I will review the differences, as far as I can tell, 
does the current API does have a clean separation between the
implementation and the inteface? 

Plus I would like to have a clean model for scripting. It will be
easier to aggree on a simple new model, and modify existing code to
work with it than to try and upgrade the existing.
