That doesn’t seem like a sustainable alternative. In the case you are describing, the productivity boost is highly dependent on actually having the right people within ear reach. You are relying on the right people happening to hear other conversations. What if your team is large, so that even if you are all in office, the chances of stumbling into the right conversation is lower? What if you are grabbing lunch, or in the bathroom, or meeting with someone else when that conversation is happening?

The most effective solution in my experience has been when working remote, and having a culture where a team has open discussions on their own Slack channel, with threads for particular conversations. That way, everyone can contribute to the conversation, it’s asynchronous so you don’t have to be in exactly the right place and right time to participate, and people can go back and review details very easily if needed.

You are right that that doesn’t apply if the conversations are happening in private DMs, but that’s a matter of team culture. You have to be intentional in a remote setting, just the same as you do in an office setting. But if you are it can work very well in my experience, perhaps even better than in person.

IME a lot of the really useful "in earshot range" conversations are those that were intended privately but were overheard by someone that has an idea.

Engineer A might go to engineer B to ask B on how to do X. B is being asked because they are usually knowledgeable about similar topics. In this case they don't know.

In slack A would message B directly. B answers that they don't know.

In the office C might overhear it and have an idea and chime in.

I think this unintentional broadcasting can be really helpful to productivity and spreading ideas. It just doesn't work so well in a messaging app.
