I suspect you have never had your bike go into a heavy speed wobble going down a hill due to frame flex when pulling a gear trailer, or heavily loaded with panniers or loader with panniers while pulling a 4 year old on a ride behind bike? Trust me if you had faced any of those you would understand why frame flex is a concern.
