I guess by using the word "fair" I may have caused the discussion to focus on the wrong idea.

It is about what is acceptable to both the employer and the employee. The employee would like the freedom to WFH but the employer consider it a benefit that come at their cost and thus do not want to grant it. As shown by other professions, the idea of WFH is entirely new and rarely if ever granted or expected to most professionals. Software devs are in a unique position to demand and potentially getting it does not make it any less exceptional and a huge ask for the other side of the negotiation.

Whether it is really good or bad is not the point I am making.
