I feel like this is the key thing.
Instead of mandating blanket policies (whatever they are) that might not make sense for every team, trust your employees to self-organize in the way that makes the most sense for them and the way they work.
I'm in the same boat, and like you, doubt I will want to work any other way again.
If you are a pro-WFO person on a team that offers flexibility to WFH or WFO, but nearly everyone but you is WFH, then what do you do?
In contrast if you are a pro-WFH person but the rest of your team is in the office, you probably don’t care as much because the benefits you gain from WFH aren’t dependent on your coworkers.
It’s mesmerizing to me how so many think office life is a necessity for data entry work
Nevermind open source developers building the software world we rely on via email for decades.
I think it's more about how cities and communities are set up with commuting in mind.
Like, I live about an hour away from my best mate, which in London may as well be Mars. Bur our offices are literally 5 mins walk from each other, so messaging 'pint?' is SO much easier when in-office.
This is just an anecdote, and things have gotten better as the city has adjusted (gotten more involved in my local community for example) but I can 100% see why people are reluctant to change.
While this may work, some companies insist DevOps means involving the entire organization and all processes, rendering the word meaningless. So in face of such inflexibility, open source software developed for open source developers works a bit differently, much more flexible.
