IETF has been successful for past 20 years in focusing on “Over the Wire” data structure. It would be so much cleaner and straight forward if the YANG modules developed by I2RS focusing on the “Over the Wire” data structure (and with NETMOD to focus on other aspects). The “I2RS ephemeral State” has the needed description for the desired behavior of the data received over I2RS interface. If we follow the IETF practice, it is good enough. Internal implementation framework is always controversial, hard to converge, usually ending up with a document (if completed) that is too big and difficult to read.
Providing some source code to show the internal implementation would be much more useful as a reference implementation. The draft-schoenw-netmod-revised-datastores-00 is on the architectural framework for datastores as they are used by network management protocols. IMHO, how data stores are used are internal to the end points.

This is a volunteer organization so usually solution proposals come from people who have created a solution and they want the WG to standardize it.

IMO, it would be in I2RS's best interests if netconf/netmod provided drafts in appropriately normative language covering I2RS requirements. However, we've been in a pathological cycle of: "We don't understand, please give us requirements" "We don't understand your requirements" "You provided examples with your requirements that appear to be attempts to change our protocol - don't do that." The most recent revised-datastore draft would be a good place to document where netmod(/netconf) believes ephemeral datastores (if that's the instantiation) could live, and also how ephemeral configuration state could interact with candidate, startup and running configuration. yang-push covers much of our desired pub-sub behavior. (Yay!) Discussion is required for how to tag security considerations impacting transport into the yang model, in particular for notification. Proposals for secondary identity and priority are also needed. -- Jeff
