I believe the ENC already has access to the node's stored value and would
display that after assignment if assigned.
I didn't consider 'cost' but it would seem that loading 'params.pp' values
is not a large cost in terms of server but perhaps just in programming.
I am just gathering that the primary thinking is that if you don't know the
values you want to use to override, then don't override.
Myself, I am trying not to longhand some of the variables and am choosing
to use ns1 rather than nameserver1
