It has been my experience, that most people purchase a medium-range fast-aperture lens, and then down the road a bit, they add a TC to the kit/gear bag.
But to find yourself suddenly nursing a 600mm f/4 with a TC on a thin-walled-camera-body. I see a chance of heart-break.
I don't understand your point. I've used a 70-200/2.8 and a 600/4 with TCs, on and off tripods. The lens mount on all bodies is quite strong.
