I’m not talking about the work contributors do, obviously that is invaluable.

But if you do a review, and you see that a function should be extracted at one point to avoid code duplication, is it really faster to tell the contributor that a function needs to be extracted there, compared to just extracting it yourself as you see it?

The value of a review is collaborative truth finding and learning. If there is an LLM on the other end, that’s just not happening.
