My objection to a PR like this has nothing to do with whether or not a human wrote it. It's that the PR is too large and complex. The reason I'd give for rejecting it would be that. I wouldn't say "it's ridiculous" as the reason. I would 100% be thinking that, though.

That’s good.

My experience is “too large/complex” provides an opening for arguementivenes and/or drama.

“We don’t do it like this” does not so much. It is social, sufficient and not a matter of opinion (“too” is a matter of opinion).
