Unfortunately that advice is not true without further caveats.

netbsd$ sh -c "printf '-V\n'"
-V

$ busybox sh -c "printf '-V\n'"
-V

ubuntu$ $ dash -c "printf '-V\n'"
dash: 1: printf: Illegal option -V

$ bash -c "printf '-V\n'"
bash: line 1: printf: -V: invalid option
printf: usage: printf [-v var] format [arguments]
