coreutils' src/true.c does exactly that - unless the user passes
an argument:

  int
  main (int argc, char **argv)
  {
    /* Recognize --help or --version only if it's the only command-line
       argument.  */
    if (argc == 2)
      {
        ...
      }

    return EXIT_STATUS;
  }

So what's your point here? File size?  Well, on my openSUSE system
/usr/bin/true needs 27328 bytes.  Compared to the 6-7K your minimal
example above result in (compiled with -O2 -g, then stripped), I'd
consider this neglectable for nowadays' RAM and disk sizes.

Re. '/usr/bin/[' --help:
I'm using it myself from time to time, as I like the terse
information there.

Have a nice day,
