George, it is not so simple.
The keppan/kishomon in classical japanese arts is not easily translated to western derivatives of gendai budo. Different times, people, culture and purpose.
Romanticism about honourable, ethical and loyal samurai of old and the arts they practised is fine, but it is romanticism nonetheless.
Honoring one's word doesn't seem like a romantic anachronism to me. It's more like a foundation stone of civilized society.
