If you keep the SOB of the author then you need to preserve its
authorship (git am --author= / git commit --amend --author=).
Unless you changed the patch significantly enough that you
simply credit with something like "Original-patch-by" and you become the
author. This is left to personal appreciation, I won't mind
in any case.

But there is no middle ground :)
You also need to keep the SOB chain in order. The above SOB chain
suggests I'm carrying a patch from you.

Just saying that so that you make the maintainers job easier ;)
