My personal opinion (but I can be wrong) is that such feature would only 
be accepted by operators only if there is some termination period 
defined when you create a dedicated instance.
Again, what happens when the lease (or the lock-in) ends should be 
defined by the operator, on his own convenience, and that's why Climate 
is behaviour-driven by configuration flags for lease termination.


Back to the initial subject, I think that's pretty good having such 
dedicated instances model in Nova (thanks to an API extension, which 
could be non-core), but the instance lifecycle (in case of termination 
period) should stay in Climate, IMHO.
