Why is Every Race's Sit Emote at Chairs and Benches so Boring?

[Zuellni]

Why is it that when any race sits at a bench or chair, their posture is so prim and proper as if they're expecting the Queen? It's so unnatural.

There are obviously more interesting sitting postures in game as many of the NPCs have them. Can't we have more natural and lively sit postures at benches and chairs like the ones NPCs have?

Just look at this screenshot, player character sit posture is just so boring compared to NPCs.
