Many of Discourse’s features on the admin settings page are best ‘on’ or ‘off’ depending on the forum, yes.
So, maybe this might be better as a plugin rather than a core feature that can be enabled or disabled. I guess something for the devs to decide. I think it’s a feature that worth using on some forums. I, personally, love data like this. I would never use it in order to spam a forum or try to boost my numbers. But it’s “satisfying” to look at and adds to the sense/feeling of members’ contributions to the community. It can include the option to enable it for Trust Level X+ members. In my case, I would allow members who are Trust Level 2+ to view it.
Similar to Category Badge Styles no longer being part of core Discourse. But an option for those forums who would like to make use of it.
