"and addressing the unique challenges of AI-generated content"

What is unique enough to warrant a special license? Both people and AI write good and bad code / exploits. They both crib and plagiarize. Some people and models are smarter than other people and models. If you ask a model to write the same thing twice you'll get two answers, so recording the model metadata is of questionable value.

Either the change is good, and should be kept, or it is not.
