LL_code does not use SystemCoreClockUpdate?

Using:

Truestudio for STM32 v9.0.0.0

STM32CubeMX v4.25.0

STM32F100C8

LL_drivers only

In stm32f1xx_ll_utils.c the SystemCoreClock variable is set directly:

void LL_SetSystemCoreClock(uint32_t HCLKFrequency) {

    SystemCoreClock = HCLKFrequency;

}

Instead of using SystemCoreClockUpdate(), why?

STM32CubeMX does not set the symbol HSE_VALUE and this causes SystemCoreClockUpdate() to fall back to a default of 8000000 for HSE_VALUE which may be correct... (it wasn't for me)
