I'd rather not though if the description= approach is acceptable to you, since adding headline= would add more complexity to an already complex ArgumentParser constructor.

Instead of adding "epilog", "usage", "description" to constructor, you
could just add one "usage_template" with these substitution variables,
including "version".
