It won't be for everyone but there has still been a huge revolution. Many businesses didn't even have laptops for employees before. Having the technical infrastructure makes it much easier to allow 1-2 days per week from home.

I've also seen WFH advertised much more in job ads. That in turn probably means that more candidates ask for partial WFH as part of their decision to join the company. In the end, that will drive change even if some managers object it.
