Serializing Subscription resources without including "status" field?

[larsks]

I would like to serialize a Subscription resource to YAML using code like this:

	subscription := operatorsv1alpha1.Subscription{
		TypeMeta: metav1.TypeMeta{
			APIVersion: operatorsv1alpha1.SubscriptionCRDAPIVersion,
			Kind:       operatorsv1alpha1.SubscriptionKind,
		},
		ObjectMeta: metav1.ObjectMeta{
			Namespace: namespaceName,
			Name:      pkg.Name,
		},
		Spec: &operatorsv1alpha1.SubscriptionSpec{
			Package:                pkg.Name,
			Channel:                channel.Name,
			InstallPlanApproval:    operatorsv1alpha1.Approval(subscribeFlags.Approval),
			CatalogSource:          pkg.Status.CatalogSource,
			CatalogSourceNamespace: pkg.Status.CatalogSourceNamespace,
		},
	}

	operatorsv1alpha1.AddToScheme(scheme.Scheme)
	corev1.AddToScheme(scheme.Scheme)

	serializer := json.NewSerializerWithOptions(
		json.DefaultMetaFactory, scheme.Scheme, scheme.Scheme,
		json.SerializerOptions{
			Pretty: true,
			Yaml:   true,
			Strict: true,
		})

	if err := serializer.Encode(&subscription, os.Stdout); err != nil {
		return err
	}

This works, except that operator-framework/api defines a Subcription resource like this:

type Subscription struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata"`

	Spec *SubscriptionSpec `json:"spec"`
	// +optional
	Status SubscriptionStatus `json:"status"`
}

Which means that the serialized output always includes a status element with a null status.lastUpdated field. Submitting the serialized manifest fails with:

error: error validating "STDIN": error validating data: ValidationError(Subscription.status): missing required field "lastUpdated" in com.coreos.operators.v1alpha1.Subscription.status; if you choose to ignore these errors, turn validation off with --validate=false

Is there a canonical method for serializing these resources without including the status field? Is there a reason that the Subscription type isn't defined like:

type Subscription struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata"`

	Spec *SubscriptionSpec `json:"spec"`
	// +optional
	Status *SubscriptionStatus `json:"status,omitempty"`
}

If the Status field were nil-able, it would be easy to get the desired output.
