Correct! With HLF v2.x external builders and chaincode as an external service, we can easily migrate to remove the dependency on usage of docker socket. That is definitely one of the ways!

Apart from this, I wanted a generic call from HLF maintainers on this topic - as it would be affecting all the HLF users to migrate from internal builders to chaincode as an external service. I consider that it might be simple, but it incurs cost in production stages and also multiple channels of communication if the setup is hosted on cloud compared to on-prem. 

I am not sure of the exact deadline we should be looking for from Kubernetes on this, but I think some sort of modification or highlight is required for sure - for everyone to be supported and migrated with ease.
