Before open Boxcutter, install ClusterExtension. Then enable TP, and open Boxcutter feature gate, the existing ClusterExtension cannot be deleted, and there are many logs           

Cluster version is 4.21.0-0.nightly-2025-10-07-171402 

    always

    1. install some clusterextension
xzha@xzha1-mac ocp-84929 % oc get clusterextension                 
NAME                INSTALLED BUNDLE         VERSION   INSTALLED   PROGRESSING   AGE
extension-80117     nginx80117.v1.0.1        1.0.1     True        True          39m
extension-84930     nginx84930.v1.0.0        1.0.0     True        True          3h38m
extension-logging   cluster-logging.v6.2.5   6.2.5     True        True          3h41m


    2. enable TP, and open Boxcutter feature gate
2.1 create ClusterRoleBinding
xzha@xzha1-mac boxcutter % cat rb 
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: operator-controller-boxcutter-cluster-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: operator-controller-controller-manager
    namespace: openshift-operator-controller

2.2 enable TP
2.3 modify deployment operator-controller-controller-manager, add --feature-gates=BoxcutterRuntime=true 

oc patch
clusterversion version --type=merge -p '{"spec":
{"overrides":[{"kind": "Deployment",
"name": "cluster-olm-operator", "namespace":
"openshift-cluster-olm-operator", "unmanaged": true,
"group": "apps"}]}}' 


oc delete
deploy/cluster-olm-operator -n openshift-cluster-olm-operator 


oc edit deployment
-n openshift-operator-controller operator-controller-controller-manager 

  
3. delete extension-80117, but failed


4, check log
