This doesn't seem a reasonable notion of "out of the box": trying to use an officially unsupported distribution that doesn't include new binary blobs for new hardware is an experiment, not an update that is expected to work flawlessly: and since the binary blobs are working well and readily available the blame is split among the optimist (mostly) and Debian, not AMD and other driver authors.
