Good questions! So currently only Daily/Weekly/Monthly Users are being tracked by these kinds of custom_jsons and I'm planning on keeping it that way for the time being.

Now regarding the active_user that was just some last_minute thought I wanted to add to see what the feedback is. I'm not yet sure how to best utilize it, as I don't want to go too much off-chain. The idea was that apps are able to broadcast this custom_json if a user is doing any actions. For example logging in, logging out, etc etc
