qemu-img convert (without -n) can often be replaced by a combination of _make_test_img + qemu-img convert -n. Doing so allows converting to protocols that do not allow direct file creation, such as FUSE exports. The only problem is that for formats other than qcow2 and qed (qcow1 at least), this may lead to high disk usage for some reason, so we cannot do it everywhere. But we can do it in 028 and 089, so let us do that so they can run on FUSE exports. Also, in 028 this allows us to remove a 9-line comment that used to explain why we cannot safely filter drive-backup's image creation output.
