Ok, these are all good points, thank you for sharing it. Just as the ones by WJW. More broadly my underlying point was more as "don’t blindly follow the herd obedience". If there is a small black box in multi-million generator stream process, no one of course want to be the guy unplugging it just to see what happens. On the other hand, if really no-one knows the real impact of such a black box, given the resources at play, risk management should induce an audit and possibly a replacement management. To my mind that sounds very different from "no one know why this thing is there, those who dare to ask will be chastised with a burden of proof to carry alone".
