NEW IE box model

The new IE box model
http://msdn.microsoft.com/workshop/author/css/overview/cssenhancements.asp ,
does not include border and padding in the box width. Although this change
is compliant with CSS1, I really liked the previous implementation better,
while I think that the specs where going to change (in other words, I
remember a thread but not exactly what the outcome was) and include borders
and padding in the "width".
What are the plans on this subject?
