Fair. The study is backed by a human being who stands behind every number. And absolutely, use whatever tool you like.

Referrer-Policy shows it can work. When the header is missing, browsers fall back to strict-origin-when-cross-origin. 86.6% of the sites we scanned don't send it, and we didn't count that as a failure for that reason. The other headers don't have a safe default like that yet.

Thanks, glad it helped!
