I'm going to actually disagree with what your table says and make the argument that gesture in concept art is actually highly important to know, not just moderately. 

A character's pose says so much about who they are as a person. How they hold themselves is key to knowing what they are about without ever having to read anything about them. Do they stand rigid and confident? Or are they classic evil genius type with a stooped posture? Are they hands-on-their-hips assertive? Or do they keep their limbs close by, making themselves small because they are shy? I could go on and on with examples of what pose and gesture tells us about a character.

The thing is, the always front facing neutral poses don't really tell us anything. If anything, it just makes these characters seem all the same.

3/4 views are great because you can inject so much more story and personality into your character. You can actually argue that gesture helps in the 'problem solving' that concept art is. Concept art isn't just about clothing, etc. It's about immediately being able to identify who the character is and what they are about.

A collection of concept art I always go back to is the character designs from Horizon Zero Dawn. There's lots of them, and each character has a pose where you can just tell what their vibe is based on how they stand, or what they do with their hands.

You can argue that you don't need to do this because it isn't your priority, but the problem solving of concept art and character design is showing us who these people are based off visual cues, and poses/gesture can be your biggest ally for helping achieve this.
