I agree with Arnout here.

However, from a purely pragmatic point of view, I see that it is totally
useless in practice, so I would not mind we drop them.

And in retrospect, I think it *is* better that we do drop them. If the
top-level option loses that dependency, then it is 'easy' to detect it
has become mandatory for a sub-option, because the autobuilders will
fail.

However, if we repeat the dependency and the top-level option lses it
and we forget to remove it, we will never realise that the sub-option
shouldalso lose it.

I agree with you. Whatever we choose, we should do it consistently.
