I think it's just the equivalent of "you can't stab someone unless they give you express prior permission to do so". It may technically be less restrictive, but in practice noone is ever going to opt-in to that without coersion. Of course, in actual practice, we'll probably see a dozen different loopholes inside a year, but I'm willing to give them credit for at least pretending to fix this particular part of the problem; it's just matter of keeping up the pressure and momentum.
