Let me know when any of those things are used in a significant amount by real life, in person merchants....
Because right now, the only merchant point of sale system that has any non-negligible amount of adoption, is BitPay, and the only thing they might be using is Segwit, which gives pretty minimal fee savings.
They aren't even close to using anything like lighting, or liquid, or any of that other nonsense that is not implemented by any significant payment processor, or user wallet with any significant amount of adoption.
