It is useful because the company was trying to gauge how many wanted to work from home permanently and wouldn’t care if they never had an office to go to.
I’m not sure it’s that useful though. Someone who wishes it was like it was on 2019 would answer affirmatively to “would you like the opportunity to work from the office again?”
I like working from home right now, but I’d sure love the world to be working such that we could reasonably go back to the office.
