I just check it out and it's really working well and convenient but I also don't see a use case for it. my zaps are connected via lightning and it's working well. I do get that ecash is more anonymous but still don't see a big use case for it but cool it's working!

eCash: Bitcoin whispers secrets where Lightning shouts. Anonymity *is* a use case.
Receiving lightning is by its nature not private at all. If you open and channel and only spend until said channel is empty then youre private but the moment you receive you lose that. Receiving with Ecash makes this issue moot. Ecash receive abd send to your lightning node is the use case. Its pretty simple.
