Yeah, my response to the original question was going to be something like:
"If the scheduler was staying in Nova, it would use NovaObjects like the
rest of Nova. Long-term Gantt should use whatever it wants and the API
between it and Nova will be something other than RPC and thus something
other than NovaObject anyway."
I think the point you're making here is that the models used for
communication between Nova and Gantt should be objecty, regardless of
what the backing implementation is on either side. I totally agree with
