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.
The threshold for modifying commit object is high. This is an
ABI-level change, something to do if there is no other solution.
Author and committer include datetime in the contents of the
field, which is used by Git for heuristics limiting walk. Coauthor
would have the same date as author, isn't it? If, after long
and involved discussion, we didn't add 'generation' field (for
easier cutting history walking), what chance adding 'coauthor'
has.
OTOH it would be nice to have support for .mailmap, and for
grepping... but the former could conceivably be added to the trailer
tool, the latter can be done with appropriate regexp in
"git log --grep=...".
I wonder what would break if one used 'Name <e@mai.l>, Name <em@i.l>'
as the author...
