There is no guarantee that all underlying vectors are of correct length if shares[0].len() >= threshold is satisfied. IMO it is better to move that check to the .map() call below. I guess this pattern might be repeated in a few other places.

I wonder if we could hide the deprecated commands from help, but still have them supported in the CLI.

Can we remove them altogether once we have tested the new ones? I do not see much value in keeping those, and we would have to maintain more functionalities.

Here I am keeping the old commands for compatibility reasons and I would like to remove them if not needed, but I think they are used in tests at the moment.
Intermediate steps outputs (generate shares, tally private vote) are only needed for inter-command communication, it probably makes sense if the format is fixed (i.e. always in json)
Working on decrypt shares I got a bit confused by
Vec<Vec<Share>>orVec<Share>since it's not obvious what the structure of that is, and they actually mean different things in different contexts (e.g. isVec<Share>all the shares for a vote plan of a committee member or is it all the shares of multiple committee members for a single proposal), so I added some more types to clarify that.This pr is becoming quite big, I don't know what the policy is, if I should split it up or navigating diffs by commits is enough.
First step for #2972
