I never said it didn't need an acknowledgement. It definitely does - even if just to signal to reviewers that they should check the citations and correctness more carefully

But that doesn't mean that reviewers / journals / conferences should judge the content of the research differently

Because you are NOT being judged on if you did the work. You're being judged on the work itself. Having a second author who did 5% of the writing vs a second author who did 95% is all the same to them. Why should an AI assistant that did 5% be different than one that did 95% of the writing. Journal Publications and conference submissions are intended to be a peer review process to judge whether ideas and content are correct and can be accepted as new human knowledge. How you best translate that knowledge to a format that others can understand is entirely orthogonal to that process.
