You're not the only one to comment this, but from what I know per review is a long iterative process, wher reviewers raise objections and submitted respond with edits.

So, what you're suggesting seems a lot like shipping code before code review, and seems to have many of the same problems. What do you do in the long period before critical issues have been addressed? What do you do if the submitter just says "fuck you, my code works, I have more important things to do"?
