I do not think that this is a well-formed question.

It directly states something that has not been well defined (or even  
accepted) by the Forum.  Specifically: it is *by no means guaranteed*  
that you will get higher performance by disabling certain MPI-3  
features.  Heck, we don't even know precisely what MPI-3 features will  
exist!

The others questions contain at least a hint of context so that  
respondents have a clue as to how to answer.  This one explains  
neither "subsetting" nor "assertions".  I suspect that 95% of  
respondents will not know how to answer.
