How about "not yet"?

Needing to do this filtering in script is clearly a spec bug. QSA is  
already littered with them, but an inability to filter an intrinsic  
property of a tag in the query language that's native to the platform  
is tactable. We just need to invent a pseudo-property for elements  
which can be matched by a ":not([someProperty=<your_ns_here>])".

So they obliquely pointed out a spec bug. Don't get me wrong, I'm no  
lover of namespaces. Frankly I think they're a bug. But SVG is stuck  
w/ 'em until it can find a way to evolve out of the XML ooze. Until  
that time, we must surely be able to do better by folks who want to  
try to make the platform feel unified, no?
