But I also think that if a maintainer asks you to jump before submitting a PR, you politely ask, “how high?”
On the one hand, it's lowered the barrier to entry for certain types of contributions. But on the other hand getting a vibe-coded 1k LOC diff from someone that has absolutely no idea how the project even works is a serious problem because the iteration cycle of getting feedback + correctly implementing it is far worse in this case.
Also, the types of errors introduced tend to be quite different between humans and AI tools.
It's a small ask but a useful one to disclose how AI was used.
