The WG does not think NMDA is too complicated or too difficult for clients
to use. I disagree.
Adding more datastores and interactions between datastores will make NMDA
even worse.
Retrieval of multiple datastores so they can be compared for transient
differences is a very complex
way to convey this state information to the client.

NMDA is too server-centric already. Maximum flexibility for the server
developer means
minimum consistency for the client developer.
