Calling { stop; exit 0; } also means the job won't be considered as failed.

Returning non-zero will log an error in the log file and prevent any job
depending on the current job from starting (which may or may not be what
you want).

So in short, exitting non-zero or calling stop+exit are two different
things with different behaviours, you have to choose which you want.
