Isn't this just Microsoft Teams? Not to be a shill (I prefer Teams over Slack but don't love either). In Teams the editor box in each channel creates a new post on which people then comment. Is Slack, a channel is just another group chat. What you do turns Slack into Teams in this regard seems to me. Which as far as I'm concerned is a better system, I just wish Slack had tools to enforce it stricter ways than as a cultural rule.
