Renaming provides less than little perceived gain. It adds serious  
pain because then you must go about registering your package manually,  
you must change imports all over, and you force every package that  
depends on the CMF to do the same. Besides, the different CMF packages  
are standard Zope2 products. Leaving them in the Products namespace  
makes that very clear.
