I think you might be misremembering. IIRC, the real argument was the risk 
(albeit expressed as performance concerns) of replacing VM-level scheduling 
by image-level scheduling without further ado. I don't recall that anyone 
had an objection to image-level scheduling as an option in addition to 
VM-level scheduling. In which case one can experiment with the implications 
and learn from the change in the environment without necessarily committing 
the production systems to an unproven feature.
