+<p>ObjectMeta was omitted by mistake when this type was first defined, and was added later on.
+To ensure backwards-compatibility, we had to use Protobuf field number 3 when adding the
+field, as 1 was already taken by the request field. This is unusual, as K8s API types
+always use 1 as the Protobuf field number for the metadata field, and that&rsquo;s also what we
+do for all other Antrea API types. It should only affect the wire format, and nothing else.
+When a new version of this API is introduced in the future (e.g., v1), we can correct
+this and assign 1 as the Protobuf field number for the metadata field.</p>
+Refer to the Kubernetes API documentation for the fields of the
+<code>metadata</code> field.
