The pandemic really reinforced to me that so many of these are pointless, at least for many participants. I have played games with co-workers, gone to sleep, done freelance work, had lunch (away from my desk), and all manner of other things through pretty much every meeting over 1 hour that I have had this pandemic. Especially the ceremonies like retro (exercise in taking notes and throwing them away), sprint planning (creating a faux schedule and throwing it away as code is done when it is done), and even in many cases the daily standup. Ditto for departmental meetings.
We cargo culted a lot of processes to WFH and will cargo cult them back upon return to office. What WFH lets me do is opt out of them and just have the conversation happen in the background instead of me being stuck in a meeting room.
