Will this prevent children from using Whatsapp, Messenger, Telegram and similar because this is where "dangerous" content is being shared. How will children communicate and cooperate on school assignments if those are blocked? Will only plain/text SMS be allowed to be used by children? What if someone texts them and offers money if they meet with a stranger. Maybe it's time to age-block SMS app too. Or maybe children should not use any smartphones. Or maybe they should use a special "android for children" where only a school approved apps can be run. I don't think this age API and age verification is needed!
