AFAIK it's not so bad in single-device use-cases. I think most of the more recent failures I've heard about have all had to do with Btrfs RAID. The prevailing wisdom still seems to be that if you want to use RAID, use an md soft-RAID device or LVM under your single-device Btrfs filesystem.

RAID, especially 5 or 6 was my main concern, yes. If I'm using hardware RAID or a soft RAID under the FS, much of the promised benefit of btrfs is gone anyway. I can add to storage pools with ZFS or expand an LVM set, too, but what does using btrfs on top of anything buy me that ZFS, bcachefs, or something like f2fs does not?

Well, inclusion in mainline kernels is the big one over ZFS and bcachefs, I guess.

I haven't seen F2FS before, so I'm commenting on the basis of 30 seconds of Googling, here, but it doesn't look like it supports either copy-on-write or snapshots, which are the big selling points I've heard for continuing to use Btrfs on top of a device manager.
