I've got to say it all looks eminently sensible to me. It looks like there isn't much change for me as a participant - the biggest burden is on the RO. All the rules expect me to do is turn up and do what it's been expected that I should do for the last however many years. If that is the case than it doesn't matter to me if they have to express that in 2 million rules. What they are trying to do is write rules that stop smart are numpties from turning up with the sleeves of their cagoules cut off because "it doesn't mention sleeves in the rules."
I like the tone it is written in. It comes down to "Use your common sense. If you can't do that, follow these rules."
