I hope this is a case of Apple delaying it long enough to silently cancel the feature or completely change it to not be on-device scanning rather than Apple delaying it long enough to be well out of the news cycle and silently enable it at a later date. Both features mentioned have potential for abuse and create an adversarial relationship with ones own device so I'm not sure what they do to implement them without these remaining concerns.

A delay in either case is welcome.
