I think it can. Enough big companies have gone all in on it that backing out will be hard. If some try to squeeze employees into offices, employees will migrate to places more friendly to it. Eg: if a hypothetical company "bookface" is more friendly to WFH than a hypothetical company "pear", they pay similarly, and both have similar jobs for someone, said someone might just sign Bookface's offer and leave Pear if Pear attempts to force WFH.
