So the whole thing has gone over your head.
Data formats are irrelevant. It's a matter of data governance. If we want to do business with the EU then it means exchanging data and ensuring that the data we receive from them is subject to their rules, rules to which we, at present, contribute to making but which, in future, we won't. Not contributing to making them doesn't mean we gain your much vaunted control. It means losing it. That applies to just about every aspect of trade with the EU. That has been transparently clear from the very start.
The only way that this isn't an issue for you is if you think you don't want to do business with the EU. If that's your wish and you get your way then you'll have tipped a large part of the UK economy down the drain, including the jobs of a lot of people who voted Leave (all those car makers with EU bases currently in the UK; do you really think they'll stay?).
