The format was dropped in QEMU binary version 2.2 with commit 550830f935 ("block: delete cow block driver").
Very old backups might still include this format as a hint (the data in the backup is present in raw/chunk format in any case), but that is not an issue. Restore already checks that the target storage supports a given format and defaults to the default format of the storage if the hint does not apply.
