Reviewer: Samuel Weiler
Review result: Has Issues

I wonder whether there should be a requirement to use authentication when
making updates.  As the doc says:

   Write operations (e.g., edit-config) to these data nodes without
   proper protection can have a negative effect on network operations.

I'm sure someone will argue "if this is used in a closed network, we can avoid
the use of authentication".  Prudence suggests that "closed" networks don't
remain that way forever, and defense-in-depth is advisable.  Let's add a MUST
or at least a SHOULD.
