Could nostr ever add forward secrecy?

Forward secrecy for what specifically? Private messages?

For everything. Does a node need to know who a note came from in order to post it to the correct location?
Perhaps it’s not possible because nodes act as mail servers and routing servers both. Not a very private system.

I think you are misunderstanding nostr here. Users create events attached to their pubkey, they publish it to relays, and their followers or whoever query that relay. Relays are dumb -- they do not do anything with the events except storing & retrieving.

Ah yes. So it’s like a bulletin board.
So the node knows who posts a note and they know who requests the note. There’s no “routing” other than responding to these put and get requests.
Because of that, there’s no concept of “forward” secrecy because there is no forwarding at all.
