While I understand that it might have been considered an "exploit", I also believe that it would allow for some great puzzles, as well as alternative solutions to some existing ones, which isn't always a bad thing (especially if you think about the probability and difficulty of setting up a force-field bridge, then going up fast enough to use it, especially when it has to be several tiles long).
I was actually thinking to use this to solve a secret which, at that moment, looked as though specifically designed for this solution. Imagine my disappointment when it only resulted in a few broken limbs for my characters after falling through an "impenetrable" force field.
