I thought the "work location" feature, where you set your work location to "office" or "remote", was pretty OK for letting people know if you are in the office. People do a similar thing with slack so you don't waste time trying to find someone in the office if they are working remotely.

(Am I the only person with wired ethernet on my desk(s)? I gave up on wi-fi during the pandemic due to terrible Zoom performance, and have kept wired ever since - lower latency, lower jitter, no interference, and faster overall.)

Maybe the new bit for Teams is aggregation and tracking. That probably isn't going to have any good effects.
