As suggest on the issue, we can already distinguish special and downloadable
subscriptions on the options page by checking whether the URL starts with ~user.
But I leave it up to Thomas whether to add these redundant properties.

+    obj.downloadable = subscription instanceof DownloadableSubscription;
     obj.isDownloading = Synchronizer.isExecuting(subscription.url);
     return obj;
   }
 
   var convertFilter = convertObject.bind(null, ["text"]);
 
   var changeListeners = new global.ext.PageMap();
   var listenedPreferences = Object.create(null);
   var listenedFilterChanges = Object.create(null);
