Ah, I remember this part. But I tend to believe that this description is
only relevant to the issue of the order of Co-authored-by and
Signed-off-by, if I were the newcomer reading this for the first time.
(In fact, I actually am a newcomer compared with you ;-))

That is to say, when dealing with multiple authors, we suggest using
trailers to represent the sequence of authors in chronological order.

Then, this will facilitate subsequent readers to understand the
development history of the patch through the order of the trailers.(?)

And, aren't these subsequent examples merely confining the discussion to
these two trailers?

<changelog>

Co-developed-by: First Co-Author <first@coauthor.example.org>
Signed-off-by: First Co-Author <first@coauthor.example.org>
Co-developed-by: Second Co-Author <second@coauthor.example.org>
Signed-off-by: Second Co-Author <second@coauthor.example.org>
Signed-off-by: From Author <from@author.example.org>

Besides the submitting-patches file, It seems to me that the probability
of "Signed-off-by" appearing on the last line is much higher than in
other cases. Is this a usual practice? It seems that everyone tacitly
agreed to write "Acked-by" and "Reviewed-by" at the top, even though
they occurred after "Sob".

But of course, you have much more experience in this area, so my limited
observations may not be very representative.

Thanks!

ps. The Git project explicitly stipulates "Place this `Signed-off-by:`
trailer at the end". So at first, I wasn't quite sure about it.
