Ok.  I think nullable strings are not a good idea simply because it
means that a property can have a state that cannot be set.

How is this different from NULL links?  (Honest, not trick question :)).

Long term, I want to be able to do something like dump the current
device graph to a config file, and then use that config file to recreate
the same machine again.  A nullable property without a null
representation would not allow this.

JSON null is such a representation.
