IMO, on the topic of extending the nostr RPC with the use of binary codecs, what would be more useful than just messing around with changing something that is already widely supported, is adding new query interfaces GraphQL is pretty widely supported, and most of the back end data storage systems used by relays can have a query interface that accepts GraphQL query syntax this would actually be useful because it would give us pagination and optimise bandwidth utilization so, nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 if you are gonna mess with making CBOR client/relay encoding, consider adding a GraphQL or other more sophisticated data query protocol into the deal because it is the biggest pain point for nostr, the data usage problem of mobile apps
