There's a few major flaws or logical fallacies or whatnot in your comment:

1. "everybody all the time in favor of AI" - this is not true (objectively)

2. "This is objectively a good change because it will improve the quality of the code in the long term." - this cannot be considered "objectively" a good change because quality is subjective. Second, it makes the assumption that human written code is always (objectively) better than LLM generated, which is also not true.

But this is a software engineering project - the code is only part of the whole project / product, and the (subjective) quality of the code is only part of that. LLMs could write perfect code by whatever quality metrics they use, but if a reviewer is overwhelmed by a morbillion other perfect code contributions from LLMs it's moot.
