OneNote in a Secure Local Networked Environment

Thanks adam deltinger.  I understand that I can continue to use OneNote 2016, and we will.  However, Microsoft will end mainstream support (patches and updates) for OneNote 2016 on 10/13/2020, and will end extended support for OneNote 2016 on 10/14/2025.

I need help figuring out whether, if decisionmakers can get comfortable with the security of local files synced to OneDrive, then the functionality of the OneNote Windows 10 app will permit continued use with our current notebooks (and linked, synced files), migrated to the App.  I have seen some threads here with migration links.   Theoretically, my employees would continue to work with local files synced to a secure OneDrive folder, and work with OneNote with the linked files at the OneDrive level.  Is OneNote going a direction that might permit this?

I understand the reluctance with continuing to develop two like products, but I would be very sorry if an application as powerful and configurable as OneNote 2016 devolved into merely an educational notetaking app.  Thanks again.
