Deploy Operator through OLM that selects only one namespace

How to implement a specific feature

Question

What did you do? I'm trying to modify an operator CSV, that it would support deployment on only one selected namespace, using OperatorHub UI. I configured InstallMode CSV section as such:

  installModes:
  - supported: true
    type: OwnNamespace
  - supported: true
    type: SingleNamespace
  - supported: false
    type: MultiNamespace
  - supported: false
    type: AllNamespaces

And the OperatorGroup associated with this operator/subscription is configured with spec.targetNamespaces:

apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: "${TARGET_NAMESPACE}-group"
  namespace: "${TARGET_NAMESPACE}"
spec:
  targetNamespaces:
  - "${TARGET_NAMESPACE}"

What did you expect to see? I expect that the operator would be successfully deployed on the cluster, on the provided TARGET_NAMESPACE value. The rationale of using this feature is that users will be able to install the operator only at a single namespace, and the default option would be greyed-out in "Operator Subscription" page in OperatorHub UI . This functionality has been adopted by many operators, e.g. 3scale:

I expect our operator to support installation on a single (chosen) namespace only.

What did you see instead? Under which circumstances? Upon subscription, I got the following status & event:
