Thanks for collecting them here!
I think this might be at odds with the general population’s assumption, in a world where we all now have many years of whatsapp chats that we can dive into for xyz reason. I think Messages and Chat map rather naturally to e-mail and instant messaging, with the twist that you can invite somebody into a Messages conversation and they automatically have access to the whole history, unlike with e-mail where they only have it if it’s copied on the bottom of the last e-mail sent, and that chat history gets lost.
That’s true, more and more. But history is retained. And Facebook has made attempts to reintegrate some form of chat into groups, channel-style. In my community, we rely very heavily on group discussions on Messenger, for moderation or real-time discussions about how to manage this or that situation in the group. We then (therefore) also rely very heavily on the chat history to recall what was decided about a case, or if a troublesome user already created trouble in the past. I’m aware this is moot with all the wonderful moderation tools Discourse gives us (user notes and stuff). But I’m definitely dealing with a population that is used to instant messaging, and I’m a bit worried about turning it off (very tempted though).
All that would be missing is the ability to display full-page like current messages, and formatting. Could we have the best of both worlds?
