Hmm, I think there has been a significant miscommunication about the purpose of the `source_hidden` and `outputs_hidden` metadata.
Here is a summary of my understanding: https://github.com/jupyterlab/jupyterlab/issues/2740 I remember us specifically talking as a groupt at the in person meeting and it being said that the entire purpose of persisting this metadata was so that nbconvert and other tools could work with it. nbconvert may have different ways of hiding content based on tags, but I don't see why it wouldn't respect this notion. More importantly, metadata state that is stored in the document can't be used as the view state as it should not be shared between users in the real-time collab setting. My comments in the above issue address these subtleties. Most importantly, the PR that implemented these flags does not mention the restrictions about these not being used in nbconvert (https://github.com/jupyter/nbformat/pull/94/files). I realize you have been asking for feedback on how nbconvert handles these things and I apologize my time has been so sparse.
