IMO Good communication is really important in any team. Video in meetings for me is really useful as I can use visual cues from my team to understand where they stand, whether they agree, etc. Smiling, signalling with thumbs up/down, emoting of any kind is a really good way to pass on quite a bit of information from multiple people at once without having to unmute and speak up to voice your reaction.

I’m not sure how useful this is in larger teams where i guess you can’t have your whole team in a single window, but at least for smaller teams it’s really useful as to gauge the overall team sentiment.
