I added parameter support to my implementation (API, *not* protocol)  
simply because I found it made writing applications easier. That being  
said, I think the biggest value here is at the client API level, and  
wouldn't be troubled if it wasn't standardized in the protocol.  
Optimization seems compelling, but I would tend to agree with Andy's  
reasoning here.
