Architects ultimately have to produce drawings that can be read and understood by a person in the field. I could spend days detailing a wall or building section but if the guy in the field can't understand it then its nothing but a monument to our egos. We adhere to basic industry standards regarding format and layout but it comes down to how much or how little info we need to convey in the drawings.
Plus any licensed architect in the US will tell you that the construction industry is an extremely litigious environment to work in, and our exposure to liability is enormous, so the drawings have to meet the intent of the design without taking on the responsibility of telling the contractor how to do his job, aka. means and methods.
