* understanding the problem
* modelling a solution that is consistent with the existing modelling/architecture of the software and moves modelling and architecture in the right direction
* verifying that the the implementation of the solution is not introducing accidental complexity
These are the things LLMs can't do well yet. That's where contributions will be most appreciated. Producing code won't be it, maintainers have their own LLM subscriptions.
This would probably be more useful to help you see what (and how) was written by LLMs. Not really to catch bad actors trying to hide LLM use.
Of course, even then it's not reproducible and requires proprietary software!
This will cut off one of the genuine entry points to the industry where all you really needed was raw talent.
