I am confused by the confusion  ;)

You all know that JUNOS implemented this concept before YANG was even a thing, right?  

Admittedly, it’s not a “datastore“, but flexing the NMDA is where we can do better. 

A “with-system” mechanism could also work.  The only downside is the inability for a client to get only the system configuration, without the rest of <running>.   

Please stop stating/suggesting “config true” nodes are referencing “config false” nodes,  or that config is referencing operational state.  There is no intention to break either of these tenants here.  

I think that some folks just joined the conversation and may have missed out when we covered all this before.  

The draft needs to be updated to more clearly identify the goals.
