Yes. option a) is always better. Patchwork admin can only test option (a).
Looking forward for Thomas's cycles to check if he agee with this process.

Another option could be to have wrapper script for  git format-patch to
to add  -add-header using ./devtools/get-maintainer.sh script so that it
is completely automated if option (a) not viable.
