Hi, I'm curious why there is a need to include InferFiltersFromConstraints logical optimization in operatorOptimizationRuleSet value [1] that seems to be only to exclude it later [2]?
In other words, I think that simply removing InferFiltersFromConstraints from operatorOptimizationRuleSet value [1] would make no change (except removing a "dead code"). Does this make sense? Could I be missing something?
