There was a "meeting" startup on HN last year (several years ago?) that had such a product. Each "room" had multiple tables, which you were free to move between. You could sorta hear people at the other tables; the closer the table was, the easier you could hear the people at it. There was also a "stage" feature that allowed someone to address the whole room at once. It seemed like a pretty good experiment, but I don't think it caught on. Maybe Slack (or Teams) should aquihire them and implement something similar.
