I have never used System.exit() or sys.exit(). What is a use case where you would call these explicitly?

For example if you want to set an explicit exit code. Calling python scripts will usually result in an exit code 0 after the script is run. If you want to set a different exit code for example 1 to indicate some error occured you can do that via sys.exit(1).

Same thing applies to other languages of course.

Applications where you aren't using some sort of framework. Usually MVC or other frameworks would handle this or are designed to continuously run.

Perl is funnier, as these are valid ways of exiting with an exception:

readFile() or die;

die unless $a > $b;

exit()-ing your step-sys already seems pretty explicit...
