Feature requests should go to Uservoice https://twitch.uservoice.com/ This is a 3rd party developer forum so no one can help with that here.
As to your suggestion though, there are legitimate reasons to be in a large number of channels, and sometimes as an actual user and not a bot. Artificially manipulating the chatters list doesn’t do anything to solve the education issue of newer streamers checking the list of chatters more than they should, or putting any weight at all on how many users are in chat, as that metric has very little value.
