Yoshida doesn't want to force players to "strive" for something as it'll create stress. This is why he made everything with a 'universal' approach, so there's no rifts between the playerbase (even though it didn't fully work out.) They originally wanted to use the gambit system as they talked about it all during beta but instead uses it for bosses (that heavy scripting? It's the gambit system.)

So it's very unlikely they'll ever make these special - look at the barding, it was a wasted opportunity to make our chocos special simply because it'll have an actual "worth" to them aside appearance. They also made all mounts the same speed for the same reason.
