Allow Bots to access Emotes
Many streamers have their bots use emotes. Currently the streamer needs to gift their bot a subscription in order to do this. However, this seems wasteful and unnecessary since the bot isn't using any video bandwidth and therefore causes limited costs to Twitch.
Twitch should give emote access to all known bots, and for bots that use custom accounts (such as MixItUp bot) allow the account holder to mark those accounts as a bot (with Twitch regulating this by only allowing those "bot" accounts to view chat and prevent those "bot" accounts viewing the actual video content of streams so that the functionality can't be abused to gain free access to streams and emotes).
Much-needed feature I was going to suggest as well.
