Maybe I missed something here, but I believe it's standard that
"program --help" should result in exit(0), no matter what the program's
exitcode conventions are for live-fire exercises.  (See
handle_help_version_opts() in the bin/scripts/ programs, for example.)
Okay to use NO_ATTEMPT for erroneous arguments, though.
