The metadata field for Kubernetes resources should use json:\"metadata,omitempty\" according to Kubernetes API conventions. The metadata field is automatically populated by the API server and an empty struct should be omitted during serialization. Removing omitempty deviates from standard Kubernetes patterns and could cause issues with marshaling/unmarshaling.

The metadata field for Kubernetes list types should use json:\"metadata,omitempty\" according to Kubernetes API conventions. This is the standard pattern used across all Kubernetes API types and ensures proper serialization behavior.

According to the Kubernetes API conventions, this optional field should have been a pointer field without omitzero.
