I wouldn't say that. We were sent home to protect us and our community. I don't think WFH execution at Google has been better than anywhere else. My experience on a team that did embedded/hardware work is I suppose an outlier, but Google has policies like "no source code on laptops" and the like that make remote work tricky in many circumstances -- none of that changed. I am however much happier now that I've transferred into a more traditional cloud-based org.

Myself, I am looking forward to a return to the office, 3/5 days a week, despite me having a long commute and driving giving me back pain: because this last year and a bit has not been pleasant at all.
