I don't think Kras was "canonically unnamed:"
What I meant was that Kras is Kras in the same sense as James Kirk is but an impostor and is really named William Shatner... Credits aren't part of the Star Trek universe, and thankfully so, considering the number of spelling errors there.
the Klingons becoming all about honor and the Romulans being more pragmatic
Umm, the TOS Romulans seemed to be a textbook case of "pragmatism" in warfare. Not only did their combat tactics depend on classic treachery (invisibility-assisted surprise strikes in "Balance of Terror", superior numbers in "The
Enterprise Incident", superior numbers and an ambush in "The Deadly Years", and in all the cases the Romulans were illegally in forbidden territory without declaration of intent), but the Romulans themselves spent most of their onscreen time backstabbing and contemplating high treason!
Klingons never "inherited" such depths of dishonor in the transition to TNG, and indeed they would have a case (even by human standards) in claiming that Romulans have always set the standard for utter lack of honor.
