Ya, I used to hate working form home and HATED when my co-workers would (fortunately that wasn't very often). However, I'm LOVING it now that everyone is working from home. I find it crazy awkward when just one or two people are on a screen. It's hard to describe why but I know it's a common feeling. I've even heard of mixed office/remote teams will do all meeting over video chat, even the ones in the office, as it puts everyone on the same level.
Yes, at least one of the teams I worked with--where admittedly most people were remote--had a pre-COVID policy whereby if anyone was calling in remote, everyone had to use their own screen. No calling in from a conference room.
