I think we need to scrap the concept of a channel, and everything should be a thread instead. You can categorize/tag threads (why not automatically based on groups of users) and they can show up as a feed similar on HN/SO/Reddit, but in a sidebar so you can easily swap between them. If you're imagining how that would look, no need to look further than an email client. The advantage of it being threads with tags/categories is that it makes it easy to move one thread from one category/tag to another (for example moving the conversation from DEV to SRE) without loosing context/history. Then there's no aside conversation, because everything is an aside.
