Yes. It's silly but relays like nostr.mom and nos.lol ask for PoW for Kind 24133, damus and nostr.band quickly starts to rate limit, and as you said, a lot of clients won't do auth. Also there's mostly no easy way to whitelist specific pubkeys as a lot of clients use random client keys. This is my main problem with supporting NIP-46 (and NWC as well) with Haven. For most clients to work properly I would have to allow everyone to write Kind 24133 notes. Shouldn't he a major problem given that these are ephemeral, but still... We need better NIP-46 libraries for clients so that I can at least require AUTH and whitelist a few client pubkeys.
