The CRD schema defines
exporterastype: objectwith no properties specified. This means Kubernetes will not validate any of the exporter subfields (enabled, image, env, resources, etc.). The schema should be expanded with proper property definitions to enable server-side validation and prevent misconfigured exporter specs from being accepted silently.
