I am by no means an expert, but I seem to recall that some non-dedicated flash units apply a very high trigger voltage between the hot shoe base and the central contact. These voltages may damage the sensitive electronics in modern electronic cameras. The flash connector at the side of the 5D body is made to withstand considerably higher voltages.

That’s a valid point. I use a later model Vivitar 283 with low triggering voltage (earlier ones were higher) and for my Novatron studio flash I add a small adapter between the power pack and the camera which reduces the triggering voltage ‘seen’ by the camera. I would, however, be interested in a definitive source for your statement that the two flash sockets on the camera differ in regard to voltage sensitivity.
