There's an ecosystem around org-mode that's developing. I made a client: https://demo.filestash.app/view/docs/tasks-projects.org?shar... the project is also open source https://github.com/mickael-kerjean/filestash
What Markdown has going for it is a much wider acceptance as a simple, straightforward way to work with text. Especially on modern devices, users with little or no coding background are successfully being lured into (superior!) plaintext workflows by apps with a great UI, and appear to take to it. iA Writer [A] and Bear [B] are two prominent examples of such apps, and I can't see why they would be any worse (or less popular) apps had they instead opted for org-mode behind the scenes.
This is what org-mode needs to gain widespread adoption, and I'm hoping we're on our way there.

I have been working on a Python way to import/export Orgmode files to/from an SQLite database that you can view and query in a native GUI (using Toga[0]). I was writing an Org-mode importing package for Python (to gain access to my Orgzly files and learn Python) until I found Orgnode[1]. I have the GUI table working, but I need to connect Orgnode to it and build an exporting system. You can follow this project at [2].
