This KEP integrates the Workload-aware Scheduling (WAS) APIs (Workload and PodGroup) into apps/v1 Deployments through a user-facing spec.scheduling field, allowing users to express scheduling intent such as gang scheduling, topology placement, disruption handling, and DRA resource claims. The Deployment controller creates one stable Deployment-owned Workload, while the ReplicaSet controller materializes one ReplicaSet-owned PodGroup per revision via the shared workloadbuilder library ([KEP-6089]), adapting the controller-as-compiler pattern established by the Job + WAS integration ([KEP-5547]) to the Deployment/ReplicaSet rollout, scaling, and revision-history lifecycle.
