It would worry me too, but I have to think that Canon designed the mount knowing that somebody would throw a 300 2.8 on there or something ridiculous like that. Unless there is specific language in the user manual stating that "the body should not be configured in a manner that allows the mount to support the weight of the camera..."
Agreed on the last statement. The lens mounts on the camera are QUITE strong. There are multiple 1/2 inch SS screws with industrial threadlocking compound (Canon recipe - not standard stuff) that holds the lens mount in place. Granted, as long as you don't present it with LOTS of shock or loading (like keeping it attached in a luggage case while at a luggage handling facility) then you will be fine.
About the only lens mount "snap" that I've seen was through 13 feet drops on concrete. And in the airport claim / handling facility where they're known to be "gentle" (less than 1000 Gs) on luggage. If this happens, the screws are meant to snap and the repairs are fairly easy. But it takes quite a bit to break the SS hardened screws.
Interesting sidenote - the lenses that have the plastic barrels - the barrels will snap in predetermined locations rather than having the screws break. 24-70 2.8L, 75-300, etc. The lens mount on the camera is not as fragile as most people think.
