For that one needs to know how the namespaces are used, not just how
they are implemented. There was a long discussion on this on #kernel
yesterday, by the way.

Do they? In order for that to be a "clearly", I believe one needs to
understand how namespaces are used in practice. It may not be desirable
or even possible; this starts getting into a policy decision.

I am not entirely sure what you mean with this, but it sounds incredibly
dangerous to me.
