Since private messages are unreliable for bots (and bots sending them are frowned upon - and I totally get the reason), can we have the ability for bots to send "ephemeral" messages to chat - messages that only a given user will see. This will also be useful for streamers. These can be displayed in the same way as "you can now redeem X award" or (better) like "You have gotten drop X/hype emoji X" messages.
