Yes, that comment by gasche is a very good general explanation for why vibe coded slop still doesn't cut it for contributing to any non-trivial FLOSS project. When you're building towards a large feature (DWARF support in this case) it's critical for contributions to be small and self-contained so that maintainers and reviewers don't get overwhelmed. As things stand, this means that human effort is an absolute requirement.

When contributions are small and tightly human-controlled it's also less likely that potential legal concerns will arise, since it means that any genuinely creative decisions about the code are a lot easier to trace.

(In this case, the AI seems to have ripped off a lot of the work from OxCaml with inconsistent attribution. OxCaml is actually license compatible (and friendly) with Ocaml but obviously any merge of that work should happen on its own terms, not as a side effect of ripoff slop code.)
