I've already mentioned an ideological difficulty with the register, but more importantly, perhaps, in practice, the reality is that what we will trade off for the intended benefits of having such a register is a false sense of security. Of course, the information in such a document is only going to be as good as each data point within it, in the same way that a chain is obviously only as strong as its weakest link, and other similar metaphors. And so it is—and I'll sanitise the expression somewhat, but it's a case of "stuff in, stuff out." Obviously, if we're not fully able to rely upon a register as being 100 percent accurate, then it will be of limited value accordingly, notwithstanding the fact that we would of course like instinctively to be able to rely upon its contents absolutely.
