There's a lot to be said for that. Airplanes are mechanical objects, subject to imperfections and faults. Pilots, by the nature of their calling, are about learning those faults and dealing with them. I am aware of the limitations of the systems in the airplanes I fly, and take measures to account for them. The pilot should read the maintenance manual and understand what the airplane is about.
Systems knowlede, and an understanding of the limitations, is important.
