Thanks @hi-artem for the contribution. It looks very good to me. Let me test it before merging

While testing the pullrequest, I spot #558
I need to open a pullrequest with a fix (which I have locally)

Also to test the pullrequest, I wrote a updatecli.yaml which I now need to commit in the directory e2e so we catch the current regression in the futur
