FWIW, I consider ".tar.gz" (or "tar.lz", ...) as the archive format (rather than as a combination of tar and compression): since the tar format does not support random access anyway there's very little benefit to having it uncompressed (unless the content can't be compressed e.g. because it's already compressed).
