To be clear, that wasn't a criticism, just a statement that MPR provides 
additional information to process.  If the goal of exposing MPR is just to 
provide disjoint paths for failover purposes, that's a relatively simple task. 
If the goal is to select paths to optimize traffic flow across the fabric, it's 
a fairly complex operation, that I'm not sure we can provide value beyond basic 
MAD support.
