Clock tree frequency values duplication in code

Hello,It seems that most examples (stm32cubeh7) are independent in clock tree values, which is exactly the correct way to do it, yet some of the examples are using hardcoded values duplicated from clock tree (duplication) which seems like a bad idea ...

HAL_RCCEx_GetPeriphCLKFreq supports only SAI and SPI ?
