Hi all, I agree with this no. We should be careful about slop submissions, but I do not think it is justified at the moment to disallow any submissions where the PR is created with the help of AI.
The "problem" that appeared in NuttX with AI supported PR's should have been solved in a different way, with a better understanding of why it was used and how it could have been improved. This "problem" has lead to a potential leaving of one of the major contributor.
