Comment(by nickm):

 Yes, it is indeed worth having a less beautiful spec in order to keep
 backward compatibility.  Backward compatibility is a real thing that can
 affect human beings who are trying to use our software, after all.  Nobody
 is going to care whether our spec says "Then truncate this to 16 bytes" in
 comparison with that.
