I’m pretty sure there might be some arcane scripts for you that would help you. But you should clarify query a bit. What are the weird issues you’re running into? Alternatively, if you’re managing nginx and letsencrypt manually you could try:

• Caddy
• Traefik
• NGINX Proxy Manager

My gut feeling is that defederation should be done as little as possible. I’m quite new to all this, but to me, it feels like it should be user preference instead of admin/mod preference. I have no clue whether that is even possible though. Perhaps there should be more filters than just Subscribed, Local and All to alleviate certain issues.
