The whole point of engineering is about efficiency, like making a bridge that holds while using the minimum amount of work and materials. A bridge using more materials is not necessarily a better bridge.
You can often make things better by putting in more effort but it may also be counter productive, sometimes the easy solution is the best. Some ready to eat food may be better than what you can cook yourself, even some reputable chefs admit it and the efforts they save on these parts let them focus on the parts where they can make a difference.
