I worked with teams pre-pandemic which had rules to the effect of if anyone was on a video call, everyone should be on an individual video call, which I'd argue is really the only way to have the remote people be 100% participants. So, yeah, if 75% of people on a team are in an office they're forced to work as if they were remote to a significant degree whether they like it or not.
Yeah. I vividly remember how it felt to drive all the way to the office one day only to spend my day in video calls. It was essentially like working from home with a longer drive and worse lighting.
