Way too many fields are emitted, even if you did not customize them, because the structs here do not follow guidelines.
Currently prints this mess:
podTemplate(inheritFrom: '', instanceCap: 0, namespace: '', nodeSelector: '', podRetention: always(), serviceAccount: '', workspaceVolume: dynamicPVC(accessModes: 'ReadWriteOnce', requestsSize: '', storageClassName: ''), yaml: '') { // some block }
Cleaned-up behavior should be verified with SnippetizerTester.
