That's one of the main reasons for forcing everyone to be present in a very small number of locations. The very logical "I'd just be on Teams for meetings, anyway" reason Steve Squeri mentions starts to go out the window because more of your team would be physically present in the same location. Instead of twelve individuals joining a call, you'd have, say, three groups of four.
What's funny about that is folks will probably still prefer not to meet physically. I worked for a place that went totally "open office". My co-workers' backs or sides were literally less than ten feet away, completely in the open. How did we communicate? IM. We never once spun our chairs around and "huddled".
Collaboration, the measurement of which is highly suspect, will not increase.
