This is very nice! I wonder if it could expand into relay selection...

How do you pick write relays? Either try to write from a new pubkey, or sign up to one.
How do you pick read relays? Make sure everybody can write to them (when tagging you).
How do you pick discovery relays? Make sure any pubkey can drop a 10002 relay list onto them. If you can't, probably nobody else can either.
How od you pick DM relays? ....
The system would need to test relays and only offer the ones that are suitable.
Most relays say things like "user unauthorized" or "you must auth"
