I agree Common Crawl is a separate pipeline, and provenance rules are worth having. But that doesn't make the search-engine mandate pointless. Search engines are a distinct, dominant training source, and they control both visibility and crawling. The mandate just says: if you train on your index, let sites opt out without being buried. That's a real removal from training corpora, not theater, and it's already technically possible. Regulating provenance and this switch are complements, not substitutes. One pipeline being hard to police isn't a reason to let search engines keep coercing consent.
