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! 💜
