I think it’s a smart idea but as we fly larger planes I don’t think it affects us as much as turboprops.

I had a baggage handler say we had 100 more bags than we had passengers. Didn’t realize it until after we put in weight and balance into the MCDU. Once they clarified the error and we redid weight and balance (100 bags lighter) we adjusted the A320 by one degree of flex temp and left.

It’s all ratios. When dealing with a 50 ton airplane it isn’t that big of a deal, but a 5 ton airplane then yes. Either way I agree the voluntary nature will negate accuracy. Sad that feelings are placed in front of safety anymore.
