Please provide an eventsub that emits unsubscribe/subscription end events
Using event sub it should be possible to ONLY use event sub to maintain a list of people subscribed to a channel. (after an initial paint from Helix)
Using the current topics it's not possible to do that.
I currently have to fetch once using helix, then use eventsub to get new subs.
Then fetch again later using helix to account for unsubs.
