In a 4.14 cluster, I'm seeing CVO hotloops on ClusterRoleBinding cluster-baremetal-operator and ConfigMap openshift-machine-config-operator/kube-rbac-proxy with empty ManagedFields.  

# oc logs  cluster-version-operator-7cf78c4f65-hfh7f -n openshift-cluster-version | grep -o 'Updating .*due to diff'| sort | uniq -c
     93 Updating ClusterRoleBinding cluster-baremetal-operator due to diff
     93 Updating ClusterRole machine-api-operator-ext-remediation due to diff
     93 Updating ConfigMap openshift-machine-config-operator/kube-rbac-proxy due to diff

CVO logs the diff as below:

CVO hotloops on ClusterRoleBinding cluster-baremetal-operator and ConfigMap openshift-machine-config-operator/kube-rbac-proxy

CVO doesn't hotloop on resources with empty ManagedFields
