One of the points of minimal-any is that the answer is not truncated because you do not want clients to automatically retry over TCP. This is to handle situations where many third-party recursive servers are under attack using one of your names, so the recursive servers are hitting your authoritative servers hard. RRL does not work in this case, because the clients are legitimate recursive servers. You want to give them an answer asap, that they can cache without hitting TCP.
