> Originally this functionality was meant to one day support more intelligent decisions in the autoscaling triggers that would react to the dynamics of the metrics changes. For this reason it was useful to keep track of the changes in the key metrics over time, without depending on any external systems.
> With the removal of autoscaling the usefulness of this handler (and the collection of metrics history inside Solr) is questionable.
> I propose to remove it in 9.0.
