First, I apologize for the long delay in my response. I only work on Git

IIRC, it was from a conversation off-list with the folks at Google's
Git-core team.

I think the convention for commit titles is

    <prefix>: <action>

so the phrase "revert doc: add discussion", where the <prefix> is
"revert doc" does not parse any worse than "doc: revert: add
discussion". That is, the <prefix> is never confused with the <action>
(they are separated by the colon).

I think the rule of thumb is to explain the goodness of what a commit
brings, rather than focus on what is literally happening. This is
because the former is more valuable. So instead of

    "git-revert.txt: add discussion"

you could say

    "git-revert.txt: advise against default commit message"

and now you don't have to look at the patch to see (roughly) what kind
of discussion was added.

OK, you may be right.

Well, even if a review makes something more convoluted, it may generate
discussion and drive consensus on the better way(s) of doing something.
I see value in that course of events.

Of course you are free to reject review comments that you truly believe
are inferior to the approach you've already taken.

But overall, when I see a reviewer's comment on this mailing list, I
assume they are trying to make my patch better. Similarly when I
reviewed your patch my intent was to provide actionable feedback to try
to make it better. I'm sorry if I did not come across that way.

I think you did the right thing by responding to my comments, and
pointing to things you found confusing.
