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 :)).
An empty string == NULL for links.
If a pointer is NULL, an empty string is returned. So get/set is full
symmetric.
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.
For JSON, but it doesn't map to a config file easily nor does it map to command
line syntax well.
