>A couple of months ago a book came out that revealed how they have not changed the control procedures for this.

That's not true. I have done something slightly related at work, which required me to contact the tax authorities to request something similar to what they did with the dividend taxes. The current wait time (12 months) has been postponed by 9 months twice because they're revising their systems and presumably doing everything manually now. When I obviously sounded dumbfounded on the phone, they explained it was because of that case.
