Several steps have been taken to address your concerns:

  - the DOM 3 parts are now used entirely by reference
  - we have attempted to clarify various parts of the introduction to  
better justify the need for the uDOM
  - we're listing a number of parts of the API to be replaced by the  
Web APIs WG's work as soon as possible (when and how depends on the  
exact timeline)

Regarding sharing a generic style API with other languages, we are  
much in favour of doing that in as close a future as can be and  
discussion has started along those lines, but until it exists we need  
a solution.

Thank you very much for your comments, please let us know shortly if  
this does not address your concerns,
