Does that means that you want to merge them together? I am more than
happy to post the slab part again ontop of that to have people reviewing it.
But if possible, I believe that merging this part first would help us to
split up testing in a beneficial way, in the sense that if it breaks, we
know at least in which part it is. Not to mention, of course, that
reviewers will have an easier time reviewing it as two pieces.
