So for a longtime this wasn't considered a terminal error?

MissingNameIdentifier is an error introduced by SetIdentifiers (Adopted CRD). It was mainly used when NameOrID was nil.
This error message fix was introduced here

// return ackerrors.NewTerminalError(fmt.Errorf("required field missing: brokerID"))
// }
// r.ko.Status.BrokerID = &tmp
// r.ko.Status.BrokerID = &primaryKey
//
// ```
//
// An example of code with additional keys:
//
// ```
//
// tmp, ok := field["resourceID"]
// if !ok {
// return ackerrors.MissingNameIdentifier
// }
//
// r.ko.Spec.ResourceID = &tmp
