It’s one thing for you (yes, you, the user using the tool) to generate code you don’t understand for a side project or one off tool. It’s another thing to expect your code to be upstreamed into a large project and let others take on the maintenance burden, not to mention review code you haven’t even reviewed yourself!
Note: I, myself, am guilty of forking projects, adding some simple feature I need with an LLM quickly because I don’t want to take the time to understand the codebase, and using it personally. I don’t attempt to upstream changes like this and waste maintainers’ time until I actually take the time myself to understand the project, the issue, and the solution.
