Another thing that just came to my mind, with regard to semantics: Will metrics be 'pulled' from a subsystem component with every request, or is a subsystem component forced to 'push' state changes to domain runtime state? The later would force the domain store these values redundantly (and stale) whereas the 'pull' semantic would more work like a snapshot of the state the each subsystem manages on it's own.
