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.
