Fair, and I've seen this, but usually it's because the reviewers are treating "I would personally prefer to do this another way" as blocking feedback, when it isn't.

Good reviews can take a light touch, in part by differentiating non-blocking ideas and suggestions from "hey I think this is a bug."

Some of my favorite reviews of all time actually don't change a single line of code, but the questions reviews ask zero in on what's going to confuse the next developer so it can be documented appropriately.
