That's a respectable goal, but I think you're way overshooting it and
thus getting it wrong. You're changing the semantics from

 "please switch this interface to that other netns"

to
 "please switch this interface *and all others on this HW* to that other
netns"

which is, in my opinion, something so much more unexpected and prone to
breaking people's setups than returning "not supported" here.
