We absolutely need to calibrate the system at all times. A system such as our trial-by-jury system requires modernization. It requires analysis to ensure that it's achieving what it's supposed to achieve. But of course we need a better understanding of it. It has been since 1980 when the Law Reform Commission made a comprehensive study of this.
We need a non-partisan understanding of trial-by-jury because, while trial-by-jury exists in our democracy, it isn't informed by democratic decisions. It's not subject to, let say, public opinion. In fact, it's supposed to guard against the exact opposite. Therefore, I very much agree with you. We need a non-partisan understanding of the system before we start pulling planks away.
