[TINYMESH] CTS pin is recommended to be observed before UART is driven on a byte by byte basis in tinymesh documents. Some other paragraph tells as if it is unnecessary and only two pins are enough. How critical is that issue?

“The communication will work without monitoring CTS, but in order to achieve minimum packet loss it is recommended to monitor CTS so your host MCU will be notified (and stop UART data) when the module (either Router
or Gateway) is busy doing transmissions (in a mesh network) or doing network maintenance, which is happening on a regular basis (automatically, to decide the optimum network configuration at any time)
