A slightly off topic comment, for where this thread has gone but
relevant if we are talking about cgroup namespaces.

If don't implement compatibility with existing userspace, they get a
nack.  A backwards-incompatible change should figure out how to remove
the need for any namespaces.

Because that is what namespaces are about backwards compatibility.
Are you claiming that namespaces are soley about backwards
compatibility?  ie. to trick userland into scoping without letting it
notice?  That's a very restricted view and namespaces do provide
further isolation capabilties in addition to what can be achieved
otherwise and it is logical to collect simliar funtionalities there.

Thanks.
