I think it's important that we don't overly focus on one isolated experience point like yours, because empirically this is highly disputed.
In my experience, information sharing has plummeted after moving to an open-plan layout. People are forced to use noise-cancelling headphones to avoid impromptu exchanges, because the impromptu exchanges are value-destructive in the first place. And when someone gets co-opted into an impromptu discussion, they try to keep it superficial and share less substantive info, to get away from the unplanned distraction as fast as possible.
Not to mention the huge increase of totally not-work-related or irrelevant distractions, like loud sales calls, product discussions that don't affect anything for my team, discussions about weekend plans, etc.
It's a very shallow notion of information sharing, which could happen asynchronously through code, documents, email, or with a scheduled video call, or a short scheduled meeting, etc.
As I mentioned elsewhere, this horribly misguided idea that somehow constant, real-time audio communication == sincere collaboration or information sharing, this idea is really destructive and doesn't map very well to how engineers actually work.
