I do like the RequiresOptIn nature of this in that it could be restricted to dev branches etc and not be enabled by default. The complication is that this requires honesty from the developer that they haven't thoroughly reviewed it 😂
Regarding the broader topic, my first thought is why is code that hasn't been thoroughly reviewed by a human ever entering a production codebase at all? We are definitely not at a point where I believe that's even remotely safe for anything serious (and yes, I use these tools every day), but even for non-serious code we're just bloating search results with junk that's not reviewed and likely not even its author's specs accurately. But hey, we can make some AI companies a lot of money, waste a lot of open source reviewers' time, and make crazy claims about what "we" or AI built, filled with red flags, on social media so I guess that's the goal for many these days. 🤷 🤦
