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.
