So seeing some cherry-picks now via MFCs, I do have one thought.
Here is a MFC by rlibby of a commit I made in head:


commit 939430f23771bb2bdd85337a58f5ba0757f60782
Author:     John Baldwin <jhb@FreeBSD.org>
AuthorDate: 2020-08-31 21:55:25 +0000
Commit:     Ryan Libby <rlibby@FreeBSD.org>
CommitDate: 2020-12-31 19:56:33 +0000

I still find this a bit verbose, but I do find that the CommitDate is
the Date I actually care about rather than the AuthorDate.  Neither one
is a "push date", but CommitDate is much closer to that.  I think I am
still fine with keeping the Author as the name and relying on the e-mail
>From to serve as the 'Commit' (probably should be "Committer") field,
so something like:

commit 939430f23771bb2bdd85337a58f5ba0757f60782
Author: John Baldwin <jhb@FreeBSD.org>
Date:   2020-12-31 19:56:33 +0000
Branch: stable/12
URL:    https://cgit.FreeBSD.org/src/commit/?id=939430f23771bb2bdd85337a58f5ba0757f60782

The mix of fields for name and date is a bit odd though.  Perhaps another
alternative might be to elide the Author fields if the Author == Committer?
That would keep a lean format when when the individuals are the same.
For that suggestion, I think you would always show the two Commit fields
("Committer" and "CommitDate") and only show "Author" and "AuthorDate"
if Author != Committer?  This would still be verbose for the change I'm
referencing here, but would collapse the detail a bit for the (current)
common case of people committing or merging their own changes.
