The main reason for this is to be able to distinguish between different errors (or "errors") based on the return code. Before this change, it was impossible to use the exit code to figure out whether a test binary failed because all tests were skipped or because exactly 4 assertions have failed. This meant that using `catch_discover_tests` and telling it to check for exit code == 4 to determine skipped tests could lead to false negatives.
