In general the plan has been to support disabling the creation of namespaces
but that is about it.  The disables are there to prevent sysadmins from
dealing with under-construction code, as in general we can not remove the code
without having lots of weird paths.

Distro's will enable these, and the incremental cost of having the enabled
is small, at least if they are built properly.  If the incremental cost
of enabling a namespace is not small we probably need to go back to the
drawing board because maintainability will be affected.
