Comment 4 for bug 1656717

To echo what Andres said, I think the juju team should revisit this before closing the bug.

We will report "undefined" for VLANs (and subnets) which are not in a space. But that doesn't mean the "undefined" space will be usable. (You cannot specify "undefined" as a constraint when deploying a node, or gathering a list of VLANs or subnets associated with the space, for example.)
