Just so this discussion has some clarity.

Nacked-by: "Eric W. Biederman" <ebiederm@xmission.com>

As a user visible entity I see nothing this container data structure
helps solve it only muddies the waters and makes things more brittle.

Embracing the complexity of namespaces head on tends to mean all of the
goofy scary semantic corner cases are visible from the first version of
the design, and so developers can't take short cuts that result in
buggy kernel code that persists for decades.  I am rather tired of
finding and fixing those.
