Introducing the STM32G0 and STM32H5 families mean that the STM8S and STM32F1/2/3 are going to be outdated and more difficult to access them from now on?
STM8S is no longer recommended for new designs as STM32C0 and other families offer very good migration options. There is no change in longevity of STM32Fx families, minimum next 10years from January 2023.
