If don't implement compatibility with existing userspace, they get a

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.
