If you don't disclose the use of
- books
- search engines
- stack overflow
- talking to a coworker
then it's not clear why you would have to disclose talking to an AI.
Generally speaking, when someone uses the word "slop" when talking about AI it's a signal to me that they've been sucked into a culture war and to discount what they say about AI.
It's of course the maintainer's right to take part in a culture war, but it's a useful way to filter out who's paying attention vs who's playing for a team. Like when you meet someone at a party and they bring up some politician you've barely heard of but who their team has vilified.
