> WindowGroups have multiple equivalent keys (start, end) that should be handled differently from other keys. The {{UpdatingPlanChecker}} uses equivalence groups to identify equivalent keys but the keys of WindowGroups are not correctly assigned to groups.
> This means that we cannot correctly extract keys from queries that use group windows.
