Well I think the point is you can’t legislate on things like style, or at least it is pointless to do so and other disciplines don’t try to. DRY is a style guid

Well I think the point is you can’t legislate on things like style, or at least it is pointless to do so and other disciplines don’t try to. DRY is a style guideline. What you can legislate/codify are procedures, safety and outcomes. So for example building designs must be signed off by a structural engineer and architect, both of whom are liable if the buildings collapses and kills someone. There are standards materials must meet and for which materials can be used. Buildings must meet standards for fire protection, air flow, heat loss etc. I’m not sure software is at the stage where we even know what to codify or what is good and what is not good.
