Robotics Systems Types

I would like to suggest a new ptoto-type for Multipie-Facial-Landmarks

My first idea would be to just send all points or publish the different face parts as individual repeated fields:

package rst.vision;

import "rst/math/Vec2DInt.proto";

option java_outer_classname = "FaceLandmarksType";

message FaceLandmarks {

    // @constraint(len(value) == 68)
    repeated rst.math.Vec2DInt points  = 1;
}

package rst.vision;

import "rst/math/Vec2DInt.proto";

option java_outer_classname = "FaceLandmarksType";

message FaceLandmarks {

    // @constraint(len(value) == 17)
    repeated rst.math.Vec2DInt jaw  = 1;

    // @constraint(len(value) == 4)
    repeated rst.math.Vec2DInt nose = 2;

    // @constraint(len(value) == 5)
    repeated rst.math.Vec2DInt nose_wings = 3;

    // @constraint(len(value) == 5)
    repeated rst.math.Vec2DInt right_brow = 4;

    // @constraint(len(value) == 5)
    repeated rst.math.Vec2DInt left_brow = 5;

    // @constraint(len(value) == 6)
    repeated rst.math.Vec2DInt right_eye = 6;

    // @constraint(len(value) == 6)
    repeated rst.math.Vec2DInt left_eye = 7;

    // @constraint(len(value) == 12)
    repeated rst.math.Vec2DInt outer_lips = 8;

    // @constraint(len(value) == 8)
    repeated rst.math.Vec2DInt inner_lips = 9;
}

Would you recommend the more readable version or the one that conforms with the original description?
