  StatusOr<gcs::BucketMetadata> patched = client.PatchBucket(
      bucket_name,
      gcs::BucketMetadataPatchBuilder().SetVersioning(
          gcs::BucketVersioning{false}),
      gcs::IfMetagenerationMatch(original->metageneration()));
  if (!patched) throw std::runtime_error(patched.status().message());

  if (patched->versioning().has_value()) {
    std::cout << "Object versioning for bucket " << bucket_name << " is "
              << (patched->versioning()->enabled ? "enabled" : "disabled")
