> Disk full is not a “corner case”. I didn't say it was. There are plenty of disk full scenarios that can be handled by BTRFS without trouble, especially when adding more disks (even temporarily) is an option. There are ways to get stuck with a full fs, but it's not a guarantee you'll end up in a "wipe and restore from backup" situation. (And to be fair, ZFS also gets very problematic when completely full; this is a general problem for CoW filesystems.)
