Are you proposing that it be "0.9.1" or that it be "0.9.1-pre.1"?
We can't go to 0.9.1 - it's not a production service and PM has stated that we can't be a "real" release yet. At that point, if we never released 0.9.0, what's the point of going from 0.9.0 preview 1 to 0.9.1 preview 1 instead of 0.9.0 preview 2?
