No, I don't, but at the point where you're integrating a UART, adding a couple of logic gates on the data input doesn't seem too much of a stretch.
I'm not saying using UARTs instead of SPI is a good idea! I'm just saying the reason that it's not a good idea is not because UART's don't have /SS inputs.

But then how is the device supposed to know when it can respond? Most uart devices don't respect flow control. They assume they can transmit at any point.
