Regulating in general causes a lot of unintended side effects, but creating new liability is certainly one of the more effective ways of generating them. In this specific case (depending on how cynical you are), you might see such a side effect as simply a potential unintended consequence, or you might see it as a potential opportunity for law makers to stealthily pass legislation/regulation they have previously failed to pass. There’s no way to say that any changes will even come from this letter at the moment. But if you think compulsory phone number registration is a bad thing (and there’s plenty of reasons to be against it), then I’d suggest you pay attention to how this issue develops, as it would be the perfect opportunity to sneak it in.
