What's expensive, and some time ago became a significant limiting factor in densely packing machine rooms, is removing heat from the room. As long as you can supply cool air to the racks they can take care of removing heat from motherboards and other components.
If cooling systems for machine rooms haven't caught up with modern systems that dissipate more heat, the direction you're thinking has merit. But I doubt there are serious limiting factors here, besides cost.

But I doubt there are serious limiting factors here, besides cost. I think we agree, but I wasn't really thinking of power-savings as the real motivation here, I was thinking of security. It seems likely we're going to see a steady steam of Meltdown/Spectre-like security concerns. We can have our cake and eat it -- isolation and all the CPU cleverness there is -- if the isolation between instances is done physically rather than with VMs.
