can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).
JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field. ([#44593](https://github.com/kubernetes/kubernetes/pull/44593))
