Yes, the same goes to the address on Signed-off-by: footers.  There
recently was a series to enhance the footer list handling (Christian
Cc'ed) for the generation and maintenance side, and I do think it is
reasonable to further add enhanced support for footers.

That does not argue for having a new "coauthor" as a new commit
object header at all, though.
