In the most recent ArcGIS Online update, Content Status has been added to elements of ArcGIS Online as either Authoritative or Deprecated. In my experience, utilizing solution deployment or testing maps and apps can generate elements that are didn't provide the desired solution or are not currently meeting the needs of the project. But these elements may have potential in the future to be explored, so they get filed away in My Content and a third Content Status might help resolve those that were needing to be actively pursued. I believe a third category will help distinguish elements being tested with a Content Status of Beta or Test.
