The Symfony Console component (in Application) contains special treatment for four/two pairs of command-line options (flags):

1. version: --version / -V source
2. help: --help / -h source

which prevents executing the entered command.

The Application assumes that any of these four switches are directed on either the app itself (the version switches) and/or the command (the help switches).

This assumption is flawed. Not all command-line arguments (the Symfony Console nomenclature is raw arguments) can be expected to be handled by the Console component base-classes directly.

Practical examples where this is flawed is when these arguments are actually entered to be processed as arguments for the command itself, like file-names or additional arguments that will get passed to another process (e.g. with composer run-script -- test --help)..
