It’s not about specific offending portions, it’s the principle of having any LLM contributions at all. There’s a group of people who are so opposed to this stuff that they object to its mere presence anywhere.
I would expect a decrease in code quality in a specific part of the repo or at least a quote/link to a changelog stating that generated code is being used as part of the fork making its case.
If they are correct and things must be done, they aren’t providing the evidence. That’s not the same as saying there’s no evidence or reason to take this stance. Do you see the distinction I am making?
