>
> The StochasticLoadBalancer maintains an enum of generator types, and then
> using the ordinal of that enum to order a list of candidate generators. This
> approach is needlessly fragile, and I think we should refactor it to use a
> Map instead.
> As a bonus, using a map could unlock the ability to support pluggable
> candidate generation if we wanted. I think that could be a nice way to offer
> robust balancer customization, without requiring that people write complex
> cost functions or an entire balancer implementation.
