Can you please fix your mail client to not pointlessly copy the full mail
header?

No. As I explained above. The Signed-off-by is a chain. The first one is
from the author. The following ones are from people who handled,
transported or applied the patch.

See Documentation/process/submitting-patches.rst the chapter:

  Developer's Certificate of Origin 1.1

for further clarification.

Unfortunately we have no canonical way to express joint develoment, but we
have used non formal tags for that, like

     Co-developed-by:

which give credits to the people who were involved in the development.

Thanks,
