🤔 I see your thought process, but ecash is just data and especially if it is encrypted data, I don't see how you could fork really, there are unofficial event types that aren't officially documented, is that a fork? Relays that support features that others don't, but unlike Bitcoin, there's no consensus thing to say "I only talk to people who do X and don't do Y"

Also, with regards to being any sort of transmitter of anything, the mint should be the first target. Otherwise everything is a transmitter including whatsapp.
