Sure, let the ones who want to stay home stay home. Meanwhile, I will have more productive interaction with coworkers, faster responses to my questions, less ping-pong during code reviews, better insight into what my team is working on, and none of that attempted Slack multitasking where each side takes 5-10 minutes to send a response.

It's been three quarters of a year. In my experience and the experience of my friends, an effective etiquette for distributed teams has not materialized. People who work effectively in an office will go back to being effective in an office. The people who work remotely from a horse farm in Hartford and pop into Zoom twice a week for some drive-by decision-making will continue to contribute that way. The ones who could have been effective working from home will get increasingly handicapped by teams who don't work well with them, and will need to decide accordingly.
