I agree that giving more control to diff generation is a good idea, and this certainly is better than the previous round that nobody reviewed before you rerolled this round.

But I have doubts about declaring "--full-diff is equivalent to giving the 'output' pathspec that is empty".

Have you thought about the interaction between this and -M/-C options?
