I'm a bit late to this discussion, and you may have already talked about
this in the ewg teleconference, but I want to throw in my thoughts.

As far as new features goes, adding ConnectX support in a point release
is a huge difference from switching OpenMPI releases from a stable
series to the .0 release of the next series.  In the case of ConnectX,
it was "just another driver" and its addition should have had almost 0
impact on anyone not using that driver.  On the other hand, switching
OpenMPI versions changes the OpenMPI stack for everyone and has the
potential to create wide spread regressions should something go wrong.
So the risk factor comparison between these two actions simply isn't
valid.  One doesn't risk regressions for non-ConnectX users, one risks
regressions for everyone using OpenSM.
