This is the documentation component of BZ1751641 - after an upgrade the StorageClass does not update the SC created by default. This issue must be addressed in the documentation.
I don't believe this needs to be in the storage section of the product documentation. We document that the default SC is owned by the Operator, and this, to me, seems to be a bug in the behavior of the ClusterStorageOperator. I've included a mention in the 4.2 release notes under the `Known issues` section. This is available for review at [1]. [1] https://github.com/openshift/openshift-docs/pull/17135
Agree that explaining this issue in the 4.2 release notes.
Content has been merged, and will be in the OCP 4.2 release notes.
