I am confused. Can somebody enlighten me how Nostr clients share relay lists (if they do at all)?

There seems to be various abandoned attempts, but nothing final.

NIP-23a/b/c: Abandoned and number reused for something else

NIP-26: Abandoned and number reused for something else

Then there are some implicit ways like

NIP-01: Defines kind-2 events to recommend relays

NIP-02: Defines kind-3 contact lists which could be used to decide which relays to read

Then there is this quite new draft:

NIP-65: Relay List Metadata by #[6]

Is this the one???

Have I missed something? Maybe some client developers can point me to the right direction? #[1] #[4] #[2] #[5] #[3]

Thanks! 💜
