> The strict placement rules are only used after the role history scan has 
> filtered the placement history to discard nodes more than once. This may not 
> be what strict placement prefers.
> There's a couple of problems implementing this.
> # persistence only logs whether a node was used or not; the saved data format 
> would need to be extended with a new optional field of placement count.
> # on a clean teardown the history is saved too many times, and will log a 
> reduced placement count as the cluster shrinks.
> It may be that the slider-managed escalation of SLIDER-799 renders strict 
> placement moot -or it may be that the behaviour proposed in this JIRA is 
> desired there too.
