@raydavis or @christianv, why the need for this file?  If I search the codebase for "status_no_reg_status_available" and get 0 results.

In the case of the alert field (seen in status.json) it's present, but wouldn't even appear if there were no alerts coming from drupal.  Following that, might I suggest that we use as few dummy jsons as possible and the same behavior if the same node can be populated or even absent?

If we have to make a new dummy field for every part that could contain null values or show up missing, that will be hard to maintain.

If we don't have a convention about whether or not nodes should appear in certain cases (I propose they simply don't appear), then the UI will never know what to expect.
