-----------------------------------------------------------
My proposal is to use picocli. HDDS-379 introduced a new simple GenericCli
interface which can support more advanced subcommand parsing. HDDS-398 also
adopts this approach.
I would implement it as soon as possible, as (IMHO) it can help a lot for the
first adopters to learn the usage of the system.
Let me know if you are planning to implement it, or we can move back to the
unassigned pool. Would be happy to help if you need more information...
