Definitely makes sense and this is something that would be necessary for my relay as I'm not looking to maintain both a GUI and CLI for the same purpose. My reasoning for possibly doing a local client was so that other people could use it using the methods from NIP-86 draft: https://github.com/nostr-protocol/nips/blob/relay-management-api/86.md . I guess I could keep a copy in a separate repo as a reference implementation if I really wanted to.
