Not sure if i'm understanding you, but are taking into account that after merging categories A and B (by way of making a redirect from A to B) someone may revert/split it by making A a different category? I think that could be the reasoning for cl_to_id. And that use case is tricky enough to break many easy solutions :)
No, that's it. I was merely considering that a category move would be irreversible, because this is how it is made at the moment : when a bot moves all articles from Cat A to Cat B, there's no easy way to undo that move.
