wbsetitem currently uses a JSON serialization of items for the data parameter that is slightly different (a bit more terse) than the export that one gets from wbgetitem. wbsetitem should support (and only support) the serialization wbgetitems gives (called "longform" by some). If "shortform" (the current form) is used, it should raise an error.
This will be a breaking change for bot authors. They should be informed on time.
