Good engineering is the differnce between code running in eight minutes or eight hours. It affects real people in real ways. It's not a "matter of opinion." any more than a bird taking a flight is a "matter of opinion."
At some point uou have to decide wheather you're going to be a politician or an engineer. You cannot be both. To be a politician is to champion perception over reality. To be an engineer is to make perception subservient to reality. They are opposites. You can't do both simultaneously.
