Yes, that sounds best. The issue with the ticket is that it breaks 
existing programs and therefore doesn't work for 2.2. However, if we 
agree that MPI_Request_free is a bad idea, we can push for its 
removal as part of the 3.0 working groups. If we succeed, we won't 
need to worry about this text.
