The new DRAAdminAccess feature gate has the following effects: - If disabled in the apiserver, the spec.devices.requests[*].adminAccess field gets cleared. Same in the status. In both cases the scenario that it was already set and a claim or claim template get updated is special: in those cases, the field is not cleared. Also, allocating a claim with admin access is allowed regardless of the feature gate and the field is not cleared. In practice, the scheduler will not do that. - If disabled in the resource claim controller, creating ResourceClaims with the field set gets rejected. This prevents running workloads which depend on admin access. - If disabled in the scheduler, claims with admin access don't get allocated. The effect is the same. The alternative would have been to ignore the fields in claim controller and scheduler. This is bad because a monitoring workload then runs, blocking resources that probably were meant for production workloads.
