I know this probably isn't the route you can go down, but I'll share my story since it's one more data point. The company I'm working for is fairly distributed across the globe, and a lot of the computer engineers are part time remote (three days at home, two days at office, say). But typically no one is fully remote at this company. I came to work on site at a city where they had an office and a few employees but it was a satellite office and I worked there for a year or so. Then the boss that was managing that office left the company and they decided to let the remaining workers from that city go full remote (it was just two of us and they didn't want to continue paying for an office for just two of us). Since I was going to be full time remote anyways I kept working for them but I can live whereever I want so I just relocated back to my hometown. I did have to push at one or two points to ensure I ended up full time remote, but mostly it was luck, in other words. This company knows I'm a good worker and responsible from my year working on site so that may be why I can get away with the full time remote whereas for new people joining a company I can see how it would be a hard sell.
