You replied to the revert email before I had a chance to message the
original commit. From your reply to the revert I assumed you were already
aware of the revert. Of course, now that you mention it, mailing the
original commit may still be useful for others.
As you are a very heavy user of post-commit review, please expect that
reverts of your commits will be more common than if you go through
pre-commit review. If you had gone through review with this change, I would
have left my concerns on the review. As you did not go through a review, I
reverted to status quo, indicated my primary point of contention, and
suggested that the patch go through review.
In most cases I would simply leave comments on specific parts of the patch,
with the expectation that they be addressed in due time. In this instance,
I disagree with the patch in concept, so that wouldn't work.
Possibly I misunderstood our review/revert policy, but I was under the
impression that it's always possible to request that a post-commit review
be converted into a pre-commit review, with the change being reverted in
the meantime.
Regards,
Nikita
