Hi, PreRulesetEvaluation is used in WindupProcessorImpl - called on all Rules that imlement that, before calling ruleSubset.perform(event, createEvaluationContext()); Is this where we technically initialize the rule subset? Because if it can be for each rule, then it would be, effectively, another phase, before Initialize. In that case, wouldn't it be a cleaner design to let this happen in rule subset specific class?
