.... and the pin loading, and the switching frequency, and the ...

There are so many things that change the rise and fall times of a pin that =
a datasheet can only specify it at one notional capacitance. And for practi=
cal uses the switching times of a pin are irrelevant. If something needs de=
fined switching times there will be a driver chip capable of driving large =
currents through a capacitive load to achieve the required times.
