I agree with the opinion.  It is a metric of the root zone as well as
existing "zone-size" which is collected only by the RZM.
I think such metrics of the root zone (if needed) should be collected
and published by the RZM.  Collecting the metrics by each RSOs is
duplication of work, as all of the RSOs serve the authentic root zone.
