Gzip compressed content sometimes gets served with no declared encoding and a media type of, e.g., “application/x-gzip”. I reckon that's more common than serving it as application/octet-stream or with no Content-Type: declared. mod_deflate could use this information to avoid compressing the response, and without sniffing the content. This more limited approach is already available through configuration, so maybe the way to handle this is via a change to documentation / default configuration, rather than code.
