How would discovery by pubkey change these bridge problems at all? Would it somehow force 5 bridges to all use the same account for the same external user? Would it somehow prevent bridge operators from editing messages arbitrarily? Would it allow a user on another platform to take over their bridged account without needing permission from a bridge owner? It would be nice to talk with a Pubky advocate who acknowledges my questions about the protocol.
