The reality for many is logging in to MS Teams or Zoom to have virtual meetings even within the office. That is what a significant number of my professional colleagues did even while at the office: many of them would just dial in from their offices, even when the meeting room was right down the hall.
A significant portion of companies already accommodate hybrid work environments, whereby some meeting attendees are remote. This would be no different.
There may be legitimate cases where physical proximity is a key advantage for a specific team, but the current WFH situation has demonstrated that those cases have likely been exaggerated, as people are demonstrably productive (in the case of my company, results in record profits) while completely remote.
