Even if everyone were to get pulled into their nearest local office tomorrow. And the majority probably do have a relatively nearby local office; I know relatively few people who moved remotely during the pandemic. I would basically never be in a meeting where everyone (or even most people) were sitting together in one room.

And to add to your point, if half the people are more are going to be on Zoom anyway, I'd rather the people who could be in a conference room together just called in individually. A number of teams I work with have that as a rule.
