Daz/Ira, thanks for this informative post and response! Personally, I would LOVE to see a Helm chart project for Hyperledger Fabric, and Ira, it would be awesome if you were to contribute your k8s controller mod back to Fabric. I strongly believe that there will be members of the community that will step up to help sustain the effort.
Creating a proposal for a new sub-project is easy: https://hyperledger-fabric.readthedocs.io/en/release-1.2/CONTRIBUTING.html#making-feature-enhancement-proposals
Alternatively, if you cannot commit to, or find others that can commit to sustaining the development/support effort, a Hyperledger Labs proposal might suffice. https://wiki.hyperledger.org/labs
