This removes the DRAControlPlaneController feature gate, the fields controlled by it (claim.spec.controller, claim.status.deallocationRequested, claim.status.allocation.controller, class.spec.suitableNodes), the PodSchedulingContext type, and all code related to the feature. The feature gets removed because there is no path towards beta and GA and DRA with "structured parameters" should be able to replace it.
