Problem with this is that you don't want to just work in an office, but also have other people from the company work with you at the office. It's different from people who prefer WFH because they don't care if the other guys also work remote or not.

Anyway, at this point of the pandemic, I'd still not feel comfortable having lunch with coworkers in a closed space. I just prefer to have lunch myself alone, or at home, than risking getting infected.
