The community hasn=E2=80=99t recognized intermediate contributions between
authorship and reviewer.  Co-Author has always been available for technical
reasons but doesn=E2=80=99t actually convey less status than Author even if=
 some
people intended it to be used that way.  I don=E2=80=99t think we should ch=
ange
that.  Stating it more clearly seems warranted.

Co-authored never means any thing different than =E2=80=9Cone of the author=
s=E2=80=9D.
It=E2=80=99s committed-by whose meaning changes in the presence/absence of =
author.
I likewise don=E2=80=99t see changing that.  For future users of this infor=
mation,
having a silent boundary at which the meaning/usage of labels changes is
very annoying.
