That in itself would probably alienate a large amount of users, especially in larger channels - the same channels where bot whispers could be viewed as ‘spam’ due to the volume of whispers.
I think us dev’s are in the same position as Twitch, lots of ideas on how to handle whispers but…no real good way. In smaller channels, slow chat may not ‘warrant’ the use of whispers but then you can run into the chat being spammed by bot response. In high volume channels, chat is typically fast enough to spread bot responses but then people can miss it, so whispers may be more useful (which then leads to one of Twitch’s current problems; how do you discern valid whispers from spam whispers beyond the report tool).
