But two, this would be a semantic shift of what classes directly inherit from `BaseException`.
It depends how you interpret that. I always interpreted classes inheriting directly from BaseException as exceptions that you almost never want to catch in an "except Exception" block.
Adding `SystemError` to that list would make it a unique error condition that doesn't inherit from `Exception`.
I would argue that the various exception classes inheriting from BaseException are already quite unique: a KeyboardInterrupt is very different from a GeneratorExit for example.
