I had a question about this in the cover letter.

It is my understanding that the SoB needs confirmation from the author
if the code was changed. I changed the code and did not want to bother
the original author, because it is my understanding they do not wish to
be contacted. I did not want to misrepresent the original author, and so
I did not change the "From:" line.

I want to be clear that I want to submit this patch the correct way,
whatever that is. I will happily take all the guidance I can get to find
the correct way to represent the work of the original author(s).

How would you prefer to account for the work by Abdiel and Boqun?

Please advise about SoB and I will correct the series.
