Yeah, I have actually frozen Minio at this older version in my stack, as "just files on disk" was the primary feature that drew me to it. I don't want my data locked into some custom format. I'd be willing to bet that ZFS will still be supported in 20 years, but I would not make the same bet about Minio.
For the same reason, it looks like Garage is not an option for my use case.
