Thanks for the review.

I started looking at refactoring (auto-linked patch above). But if this is ok to land then that's preferrable in order to keep the implementation side of RemoveDIs unblocked. I will gladly return to the interface refactor later! Playing with it and chatting offline with @SLTozer I have come round to preferring separate functions.
