Review comment:
Agree we should keep track of the mapping. I just felt we could improve the
clarity of the tracking even a bit more, but I could not think of a better
solution right now. But as I said I think we could try make it a bit more
straightforward in some follow-up.
Just to sum it up. I think it is absolutely ok for this PR, but I have a
feeling we could improve readability of this mapping **even more** in the
future.
