If someone things get-state is needed, write an I-D for it. This is
not a big deal since NETCONF operations are extensible. Note that this
is not refactoring and fine.

That said, it is fairly easy to find out where the state data is
rooted in a YANG data model. Writing a script to find the state
root(s) of a data model is not a big deal.
