But "title" and "{http://backend.userland.com/rss2}title" _aren't_ the  
same element, and the same goes for any other local name, and as such  
for anyone using a namespace aware parser (which they already should  
be seeming RSS can contain foreign content) they are totally different  
elements.

Atom already provides all this. Why do we need RSS too?

We already have a fair amount of interop. for Atom within other  
foreign documents, but not for RSS. Why do we want to add something  
else that is not already well supported? What do we gain by using RSS  
and not Atom?

That's exactly what you're doing though, putting RSS into a namespace.  
We already have Atom which handles all these use-cases fine.
