Who would need an ultra high precision quarz on an STM32 processor?

This is being used in a LoRa module (it's a Reyax RYLR896 (which is not great for my purposes ngl)). The STM32 acts as an intermediary between its UART interface and the LoRa module's SPI interface, basically doing some rough translation and some encryption, nothing major. I believe the LoRa stuff has its own crystal, so I would imagine there is no need for an external source.
