PS9: 
That's a cool idea, and so compact! I understand this patch is already in a right place in the chain: everything before is added in a separate file, so does not affect normal run?

Also it seems like for everything in the chain before, it's just corrections for commit message and the final rebasing. So the first 4 patches in the chain can be merged very soon.
