This patch lack some point: documentation, comment in source code, etc, so it's WIP patch yet, but I think that it's enough to discuss about this.
Code comments exist to indicate the intention of sections of code. They are essential for reviewers, not a cosmetic thing to be added later. To gain wide agreement we need wide understanding. (I recommend a development approach where you write the comments first, then add code later.)
