If you then go on to fly a C310, Seneca or Duchess then you SHOULD still do the SUGGESTED differences training but it is not mandated. A class rating is just what it says - a class rating and that theoretically clears you to fly any aeroplane in that class.
However, I return to my original point and ask "how many ME aeroplanes are you likely to fly as you move through the training system"? For most students that will just one.
My personal opinion, having flown pistons, turboprops and jets, is that in general the aeroplanes get easier to fly as they get bigger. Experience would suggest that the DA42 is easier to fly than a Seneca so the question is "why make getting your CPL and MEIR any more difficult than it has to be?".
