Thanks for the detailed comparison.

<scarcasm> Wow.  This is *so* much simpler than SNMP.
It feels like trying to do a high-precision caber toss.

Seriously, I think this shows how what makes sense for incremental
editing of (the representation of) a configuration isn't necessarily
going to be very pretty for shoveling it around en masse or vice versa.
It's a good reality check for those of us who heard the operators
saying that they wanted the CLI and protocol to be identical.
