Should returning be overridden at all?

[Gandalf Parker]

I can see the point. The usual method for handling spells would be moving it higher on the priority category but that wouldnt be a good idea because then AIs might use it when its not wanted.

But are there any other spells that call into a never-overriden category? If we get an exclusion for this spell then wont there be a list of other cases people want excluded? This might be another of those places where we would be opening the door to a load of IF this and IF that statements in the code which has been avoided.
