Description
I have loaded a list of objects from MongoDB: Task.objects(...).exclude('steps', 'responses')).
Having one of such documents, how can a determine that it's missing some fields which were not loaded from the database and I need to do .reload()?

Research direction
Start by reproducing the query with Task.objects(...).exclude('steps', 'responses') and inspect the resulting document object's available state. Determine whether the current MongoEngine API exposes which fields were excluded and how reload() behaves. Done means the issue has a documented or implemented way to identify unloaded fields before reloading.
