No.
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>])".
The SVG WG explicitly requested an example illustrating how to
filter elements based on the namespace URI that works in the general
case, given that there is no longer a namespace prefix resolution
mechanism supported in this version of the API.
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?

I'm well aware that with the specific markup example given in the
spec, the selector "svg>video" would have the same result in this
case, but that doesn't work for the general case, which is what the
SVG WG wanted to see.
