Great. Could you point me to how I can use this before the next official release?

I can't make this work for other versions than 2.3. Am I doing something wrong or are the config.json files for other versions simply not updated yet ?

It's only supported on 2.3.

Are there any plans to support it on other versions ?

Additions to the v3 format should be suggested on the docker/cli repo.
