I do not think that loop devices have anything to do with filesystems.
The losetup(8) manpage states :
losetup is used to associate loop devices with regular files or
*block devices* (...)
A use case for a loop device based on another block device is to create
a partitionable block device when the underlying block device contains a
raw disk image but is not partitionable (e.g. partition or logical volume).

There are other uses. In addition to the use case I mentionned above, a
loop device can also be used as a swap device when the filesystem does
not support swap files (e.g. btrfs).
