No Verb Validation when only Options are provided?

Hi,
i have configured options (-i -o -k), but when i put in a verb at the beginning, no error or similar is raised. The "unknown" verb is just ignored. Is this intended?

Start by reproducing the reported setup with options -i, -o, and -k plus an unknown leading verb, then locate the command-line parsing entry point that handles verbs. Confirm whether the unknown verb should produce an error and add coverage for the observed behavior if the project has a relevant parser test.
