Supporting that shift, PR 142014 optimized shared device lookups in the structured allocator, and PR 141831 added a warning when a device taint rule selector is empty and would match every device in…

Second, declarative API validation had a graduation wave. PRs 141967, 141677, and 142119 moved Storage Class, CronJob schedule, and Runtime Class rules from beta to stable, removing the superseded hand-written checks.
