I believe it would still be possible to correctly map browser engines by generating a fingerprint from their Modernizr profile, and compare to a fingerprint database generated from different browser engines and versions. I'm not sure, but it might be out of scope for this project?

Hello,
I don't believe using Mordernizr is the way forward. This project is an alternative to it, a discouraged one, if you have read the Readme :)
