OpenShift manages customer workloads with the label syncer. Such that it is taken care on behalf of the user. For OpenShift namespaces, this is not true. It is expected that every team decides consciously their security posture. It is not expected that customer use that kind of namespaces!

In addition, Helm doesn't support to create namespaces with labels.
How do we test this?
Should return labels that are set to
