You're probably right. How does the following reasoning sound:
SystemExit, GeneratorExit and StopIteration are all deliberately triggered by
certain well-defined elements of normal application code. That is, only
certain operations will ever result in a ControlFlowException being raised.
KeyboardInterrupt is a better fit with MemoryError and SystemError - something
that occurs unexpectedly, at an arbitary point during program execution. That
is, a CriticalError may be raised when attempting to execute almost any
operation.
