Hello! 
Thank you for sharing your work on Omd and posing this question 
afaik, omd is in need of new maintainers. There was a call for new maintainers several years ago, which I heeded to the best of my abilities at the time. Since then, my availability for helping maintain it has been eliminated by life’s demands, and my interest due to the publication of cmarkit (which I find preferable in every respect I care about).
Is there anyone with availability or interest in picking up maintenance of omd?
