Well, one may argue that people misusing the NN to have a global chat should give you a hint as a dev that there is a slight interest to have a global chat implemented.
A different one might be that there are a lot of Mentors out there that actually like to help new people and that there is an equal amount of people that just did
it for the looks and rewards, well, one may even say that SE lacks of a proper implementation to remove a Mentor from the Mentor role if he doesn't fulfill the role correctly.
Now throwing that all in the trash seems a little odd doesn't it?
