Doesn't that screw up the whole idea of checksumming etc ? In my understanding the FS (=btrfs or zfs) should have the direct contact to the "metal" (=hdd/sdd) to be fully able to detect bitrot and stuff. btrfs inside a crypted volume will work, yes, but it won't be able to see or correct flipping bits on the hardware, because the underlying layers of cryptsetup etc might hide them. Right?
