I can't speak for IEEE, but the reasons usually brought up include  
implementation costs in terms of buffer depths, and mutual jitter  
between competing traffic streams. If you have a session that sends a  
packet every 20 ms and depends on that being mostly maintained,  
having another session send packets that are 30 ms long and can get  
several into the queue ahead of you can be a real pain.
