This whole Child Safety feature was not planned to be announced yet. They tried to fix some missleading leaks. My guess is that they are now preparing well to announce everything in September.
I don’t want to be mean, but sometimes leaks do more harm than good, espcially when they don’t match what is actually coming. Many people are angry here, the most of them have not read actual technical details.
Respected people should be more responsible about what they spread.
