Thats the thing with giant PRs. They never really needed to be reviewed anyway. In cultures with strong review culture I have worked at, if you send me a thousand line PR and ask me to review it, I will look at the giant blob of text, and immediately fire off a "it's too long, can you cut it into smaller PRs?".

Because I don't trust myself to review a giant PR. It takes too much cognition to properly review it.

And now that people are making PRs with AI, this is even more important. If the AI was good enough to have coded it, please instruct it to make the changes in reviewable chunks.
