if i was running a relay and wanted to manage via nostr notes, id probably use DMs and spec out supported commands (each relay, as a service, gets its own nsec and npub). this makes configuration viable from any client supporting DMs and ive been sucessfully using that approach with bots since early 2023 

 That is a good idea, I was managing a metadata updater tool via DM and it was working great but haven't worked on it in a while or pushed up that branch. I guess I could still construct the DMs in a GUI client with buttons but like the idea of any client being able to do that.
