We discussed this and since @namespace has been around for a long time it  
would probably break more if we removed the ability to do default  
namespaces in CSS. In its almost nine years of existence this hasn't been  
a problem really and we expect it to be not much of a hassle going  
forward. Please let us know if you disagree with this response.
