Fair enough. I wasn't trying to be for or against either, and, like you, was trying to move things along and away. We, and I think here of the UK and Europe, face a lot of challenges, some unforeseen, such as the as the pandemic. Changes such as the B-thing can add a layer of complexity and difficulty, though occasionally they can streamline a solution. But these issues have so many moving parts, it's ultimately hard to judge effect and almost impossible to construct a sensible counter-factual scenario for comparison. What am I saying? Well, apart from supporting the consensus that no good can come of debating such inappropriate matters, I doubt any reliable conclusions can be reached about the effect of something one may, or may not, support!
