Quite the opposite.

This sort of comment actually indicates that the author has at least
understood some of the complexity behind the proposed changes. It is a
qualitative comment that conveys useful information to reviewers, and
even more to the maintainers of this code.

That's the difference between a human developer and a bot, and I'm not
overly fond of bots.


Without deviation from the norm, progress is not possible.
