How do you distinguish between a power play and a calm and reasoned "okay, this arrangement is over and therefore so are all of its provisions"? I don't doubt for a second that the EU's diplomats would resort to power plays and threats when they believe it's in their best interests, but dismantling the provisions of a treaty when that treaty no longer exists isn't a repercussion or a threat or bullying, it's just kind of how treaties work.
