An interesting appnote has appeared, AN5337 STM32H7 Series lifetime estimates.
It's not that usual to be concerned about the lifetime of a mcu. Megahertzs take their toll.

And temperature. 140 degrees! They are well prepared to the warming.

And voltage. Probably root cause is electromigration.
But both temperature and voltage and the huge current densities in the very narrow tracks are consequence of the quest for megahertzs.
