It didn't make WFH more viable or acceptable, it exposed the hypocrisy of employers.
You don't think that things are any easier now that most of the workforce has practical experience with video conferencing and how to coordinate with people in the same office?
I think we both learned how broadly possible it was, and also trained the whole workforce in how to do it.
I get that some people really like working in close proximity with others even if their job doesn't really require it - but this really seems to be the case of controlling employers demanding their troops trudge into to an office to demonstrate their value in person - pandemic or disability (or just the general annoyance of commuting to work and all that that entails) be damned.
Teams were normally organized so you'd need the least amount of cross office communication as possible because it was recognized how inefficient it was. So yes they were "remote" but everything was organized to make sure you need to communicate with them as little as possible.
