argp: ARGP_NO_ERRS suppresses help output

According to
http://www.gnu.org/software/libc/manual/html_node/Argp-Flags.html#Argp-Flags,
when ARGP_NO_ERRS is set, the effect is "Don’t print error messages for
unknown options to stderr". In reality when ARGP_NO_ERRS is set, all
help output is completely suppressed - --help option is still
recognized and processed, but does not do anything.

Is it intentional? My goal is to avoid errors from getopt about unknown
options and let program to handle them by intercepting argp_parse()
return code; but still using all other features Argp provides, like
help formatting.

TIA
