mainly because it already took tons of effort just to get lightning and nostr working, and adding an entire new set of primitives for dubious privacy gain isn’t super worth it for us. People wouldn’t even end up using the privacy features of ecash on nostr, you end up zapping the amount publicly anyways.

I think custodial lightning hubs work fine for nostr usecases and are simpler. Also the complexity of managing many different tokens across many different mints gets crazy fast. KISS.
