Give Players the Ability to Opt Out of Public UUID Information

I am aware that Mojang wants UUID information to be public, but this could have dangerous consequences for transgender individuals, those with a past history of stalking or harassment, and victims of bullying. Additionally, usernames in particular could reveal personal information (not related to full names) that can be used to track an individual, such as year/full date of birth, country/state, age, or abbreviated names or nicknames that stand out. This gives people with malicious intent the ability to use this information to track down the social media information of both adults and children, putting them at risk.
