I don't think it would make sense for them to now state that they're going to deliver that no matter what, because then 1. You're going to have people asking for timelines on that even more often than people are currently asking for non-phone number authentication, and if you indulge them, they're going to get angry with you for missing it. 2.

Until then, we'll probably only hear about individual problems they solved on the road to there.
