In a past life the room all the programmers was in was quiet as a library. Anything above a whisper seemed like yelling. It was terrible for collaboration and communication. We ended up going for walks in order to talk about stuff, which actually helped in multiple ways. Walking seems to stimulate the brain in weird ways and talking freely was very productive.

That said, I would not trade WFH for anything. Those walking times with co-workers was great but it's not worth being forced to go into an office every day.
