I found an use case that might be interesting for this, maybe not a moderator but an user with access to the great analytics that Discourse already generates.
Imagine a forum that uses some kind of marketing campaigns, yes Analytics is good, maybe Matomo or any other, but having the analytics built in give a more precise metric and there’s no need to run another tool for the same result.
So, having some kind of role that is able to access the admin dashboard and the metrics would be great to communities that use marketing or run campaigns to promote theirself.
