Probably I spent a bit too much time with that code, so now yours suggestion looks to me like an unnecessary step. But I will try and see how it goes, at least it should be possible to break down the patch 1 a bit more, hopefully it will help to better understand what's going on in the further patches if you're not familiar or don't remember how it all works.
