IMO the deprecated state module only needs a config=false version of the
config=true NMDA nodes.
Since config=true validation statements are not allowed to reference
config=false nodes it should
always be possible to remove the config=false nodes from the deprecated
state module.

Otherwise the config=false nodes show up twice for non-NMDA clients
because they can
read the NMDA config=false nodes just fine.  (The NMDA transition strategy
is vague and
using the /yang-library tree to hide objects is too complicated, but that
is not in scope for module-tags.)
