Very few of us have such detailed knowledge and there isn't time to do an analysis. I was thinking more of a back of the envelope calculation that no, you can't introduce a new constraint into the world financial software system in a week's time and expect everything to work something and making some kind of statement from the industry about that - a petition might work.
