In many cases, this is a power imbalance - the one paying you your salary makes the choices, so your choice is accept or leave. Most people will accept it, so it's no problem to let a few rebellious apples out. But in software engineering, where there's a ton of job opportunities, the imbalance is smaller - many people can choose to leave and go work somewhere else. A company can't survive if all its employees leave, so they must make room for negotiations. Therefore I expect that some WFH opportunities will stay - some companies will be happy to poach talented leavers.
