The problem is you could conceivably enable this in a "safe" setting like your car...only to have an embarrassing message spoken on an occasion when you have a passenger in your car.
Without sounding all tin-foil hat, how is Apple planning to prove they are honoring opt-outs? Are they going to have an independent audit or are we supposed to just trust them?
They've only ever needed a sampling of recordings to review. They were presumably drawing that sampling from all recordings before.
Now, suppose only 10% of people opt-in, although I'm sure it will be higher than that. That's still plenty to sample from.
So there's zero reason to not honor it. On the other hand, if they were sneakily not honoring it behind the scenes and that ever were leaked (which would probably happen), that would be a huge hit to their reputation, which would be a big business risk.
So for a rational corporation trying to make money, the profitable business choice is to honor opt-outs -- it's all upside and zero downside.
