Aggregates have a UUID now, exposed in microversion 2.41 (you added it). 
Is that what you mean by AZs having a UUID, since AZs are modeled as 
host aggregates?

One of the alternatives in the spec is not relying on name as a unique 
identifier and just make sure everything is held together via the 
aggregate UUID, which is now possible.
