Teams big companies are already distributed across time zones, effectively forcing their employees working remotely. It's quite common for an org to have office in NYC, in Bay Area, in a tech hub in Europe, and in an Indian city. Meetings are conducted over video conference, and communication is mostly asynchronous in writing. I don't see how that is different from WFH. Of course, local office for employees to bond and having face-to-face discussion is really nice, but there are different ways to handle that.
