You are pushing the discussion in an area that to me is pretty
insignificant, and where I did _not_ want to go. I said:

I was going to remove this code in the first place, it's just that you
didn't like the justification in the initial commit message. Fine. So
I asked you if this new commit message is OK. You said:

So let's cut this short: we agree about everything now, hardware
behavior and software behavior. Could you edit my commit message in a
way that you agree with, and paste it here so that I could include it
in v2?
