Poorjohn, no. Sadly. But as said, it's not sexy enough. It would also be risky in terms of libel, suggesting z,y or z are behaving dangerously by not complying with best practice though complying with the law. There lays the rub - the defence is always "it's legal"; so is sticking a fork in a plug socket, but it is neither safe nor intelligent, and the results are predictable. That is why the entire industry continues to have a problem, not just isolated carriers or even nations.
