Ever other system could (and does) use this as well to boost throughput by reducing speed. Or like LN does by looking up funds in advance to increase speed again. Its always gonna be way less efficient than having order of magnitude faster layer 1. and only offload micro Tx to the second layer. Also increases cost because you add additional parties in the system who wants to get paid for providing the service and liquidity. It simply can not provide a better service in the end.
