Recently, a new Hyperledger Labs proposal came in https://github.com/hyperledger-labs/hyperledger-labs.github.io/pull/176 . The proposal was for Hyperledger Fabric operators, they already might have support for 2.2 LTS release. Did the hlf-operator team reach out to Hyperledger Cello maintainers?

fabric-operator let fabric run atop k8s, which is potentially a good driving agent for Cello.
