I definitly agree with you, Mridul.

Ordering on the client side is easy and simple.
It is a fair way to share the load between clients and servers.  
Keeping the context for each client on the server itself can be very  
costly for large scale high performance deployments.
It seems also odd to block the processing on the server side for the  
sake of ordering, whereas, it can be up to the client to wait for the  
answer it needs first or to react to incoming events in different  
order, depending on the type of messages.

So, I am with you, Mridul.
