Is there a particular exception class that can be used to specify an exit code and error message, or do we need to define our own exceptions?

Right, which is why a number of us have been asking for a simple way to return an error code.

I would suspect that there are developers who have strong preferences for both, much like with `int main()` and `void main()` in C/C++.

..or even version 3
