Although btrfsck test case support pure image dump(tar.xz), it is still too large for some images, e.g, a small 64M image with about 3 levels (level 0~2) metadata will produce about 2.6M after xz zip, which is too large for a single binary commit.
However btrfs-image -c9 will works much finer, the above image with btrfs-image dump will only be less than 200K, which is quite reasonable.
