I have yet to see a client that offers a service like that or a relay that only requests certain types of information, I think its still early and a free for all and in future, we should see things become a lot more specialised and used more efficiently

Is it just me or, for now, most clients do not let the choice of what relay(s) a note should be broadcasted to?
I am using astral and snort.

Does anyone have an example of a Nostr client that implements relay choice when posting a note?
