Well, when Jeff and Bill successfully argued against a definition for atomicity of access for conflicting accesses beyond "undefined", we lost direct support for the UPC memory model.  After that, I no longer cared about ordering and Jeff was still arguing vehemently against ordering, so my understanding was that we had dropped ordering.  I am not sure why we would support ordering without an access granularity definition.

My understanding was that we were providing both 1a and 1b. Or rather, 
MPI-2 already gives 1b, and we are proposing 1a together with it (not 
instead of it).
