> Producer requests to internal topics (currently only __consumer_offset) can be disastrous.
> E.g., if we allow a message to be appended to the offsets topic this could lead to fatal exceptions when loading the offsets topic and when compacting the log.
> Producer requests to these topics should be rejected.
