ADC1 channel 0 is always on PA0. Why?

It is possible to change every other pin but not ADC1 channel 0. I wonder why. What is special in PA0 or in that ADC channel.

I am currently looking at STM32F746 but others are no different(, I think).

No, it is not. ADC inputs are connected to pins in a fixed way.
