nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc should consider the ecosystem when using MLS. I foresee a future where relay owners eventually block kind-445 under the current spec.

I think you're missing something. The entire job of relays is to RELAY messages. To assert that every app building on Nostr must figure out profitable models for relay operators is retarded.
1. This "bloat" only needs to be stored for some medium length time (a month?) then it can be deleted if relays want.
2. Each group using White Noise can decide what relays they want to use. This leaves them wide open to zap (or pay in some other way) those relay operators.
OK, I might be wrong. Let's just see how it goes.
