Topic on Talk:Growth/Personalized first day/Newcomer homepage

So I frequently update my preferences and also browse around it to see any new changes/features on English Wikipedia, I happened to came upon this "Display Newcomer homepage" checkbox so being curious I ticked it, and going to my homepage (via the link displayed left of userpage), I noticed there is a mentor thing so I read around about it and it is designed obviously for newly registered user since it's called newcomer homepage and the mentor are assigned randomly ... but I'm certainly not a new user since joining 8+ years ago and has accumulated approx. 30,000+ edits so why do I even have mentor?

For practical reasons, we have assigned a mentor to everyone. We plan to work on a feature to opt-out mentoring.
