My gut reaction is exhaustion. I would like this if folks had the time, resources, and politicians weren't so tied up in party politics.

If you have a functional legislative arm of government, then it produces too many bits of text for the average person to keep up with it, and it's not terribly efficient for them to try. I don't need to know the particulars of industrial zoning policy, but I do want it to be sensical.

And if the politicians decide to bundle things together, lots of wedging becomes available. This seems less common for single-issue policy juries (one could even constrain their range on creation).

But in RCV and good support: sure. I think it could be made to work.
