When a preventative measure very obviously won't solve the stated problem, that may not be what it's really there to solve. This is another of Google's anti-open-source moves designed to bring all Android devices entirely under their control and surveillance. It goes along with their bringinh all Android development in house and making it harder for third parties to make their own custom versions of Android (Graphene OS etc.). It also seems a little odd that this happens right when several countries are introducing requirements that users supply ID to visit websites.
